### What does this PR try to resolve?
This PR reworks `cargo-test-support` and `testsuite` to use Snapbox's
[`cargo_bin!()`](https://docs.rs/snapbox/latest/snapbox/cmd/macro.cargo_bin.html)
instead of
[`cargo_bin()`](https://docs.rs/snapbox/latest/snapbox/cmd/fn.cargo_bin.html)
which makes assumptions about the structure of Cargo's build directory.
`cargo_bin!()` uses `CARGO_BIN_EXE_*` for locating the `cargo` binary
which should be more resilient to directory/layout changes.

As shown in that link, we could make these variables available at
runtime and not need to do this. However, `cargo-test-support`, as an
API, is a bit weird in that it is baking in support for one specific
binary. This can be confusing for callers and makes it more annoying for
callers provide their own `fn cargo`, e.g. see crate-ci/cargo-fixit#7
### Implementation Notes
`cargo_bin!()` only works when being called from the `testsuite` as it's
only set when executing integration tests and `cargo-test-support` is a
regular crate.
To make this change, I introduced an extension trait `CargoProjectExt`
in `testsuite` for running `.cargo()` and implemented it on `Project`.
In `cargo-test-support` other functionality relies on `.cargo()` so
these also needed to be moved to `testsuite`
*
[`src/tools.rs`](https://github.com/rust-lang/cargo/blob/master/crates/cargo-test-support/src/tools.rs)
* Parts
[`src/cross_compile`](https://github.com/rust-lang/cargo/blob/master/crates/cargo-test-support/src/cross_compile.rs)
* I had to split this up unfortunately, as `disabled()` requires running
Cargo to check if we should disable cross compile tests.
* Other fns in `cross_compile` are used in `cargo-test-support` so
moving everything to `testsuite` would have ended up requiring moving
many things to test suite.
### How to test and review this PR?
I'd definitely recommend reviewing commit by commit.
There are a lot of diffs due to the nature of reorganizing things.
I did my best to split things things into smaller PRs but they still
contain a lot of `use` statement diffs.

close https://github.com/rust-lang/cargo/issues/14831
In this PR, we added the `cargo pkgid` support for the cargo-script.
For the package itself:
```console
cargo pkgid --manifest-path foo.rs
path+file:///my-project/foo.rs/foo#0.86.0
```
For its dependence:
```console
cargo pkgid --manifest-path foo.rs -p sqlx
registry+https://github.com/rust-lang/crates.io-index#sqlx@0.7.4
```
### How should we test and review this PR?
I have updated the unit tests and also added more test cases for it.

This commit makes lockfile version 4 the default version when Cargo
tries to write to a lockfile.
The lockfile version 4 has been stabilized since 1.78.0,
and will become default in 1.83.0.
the length of transition period is pretty similar as before.
One caveat is that in other output from Cargo,
e.g., `cargo metatada`, status messages,
`SourceID` will display in the v4 URL encoded format.
This shouldn't affect the majority of Rust users,
as `SourceId` representation should be opaque to them,
unless comparing `SourceId` across different version of toolchains.
This is for `cargo generate-lockfile` and when syncing the lockfile with
the manifest.
We still show it for `cargo update` because of `cargo update
--workspace`.
We hacked around this previously by filtering out the `num_pkgs==1` case
for single packages but this didn't help with workspaces.
We now include the prelude in so many places, this simplifies how we can
present how `cargo-test-support` works.
Yes, this included some `use` clean ups but its already painful enough
walking through every test file, I didn't want to do it twice.
This is a partial revert of ##14121
(e11d1722bb6e1e58c91adb1964993c74b45f4293)
Our focus for redacting (auto or with globs) includes
- run-specific information (timing, hashes, platform-specific wording)
- rustc-specific information
(We tend to use globs for rustc-specific information because there might
be some very specific times we need to care about some of the details)
However, "Packaged files" does not fit into any of that and, for now, we
are erring on the side of redacting less, rather than more, with the
move to snapbox.
As we see how it works out and what the underlying requirements are, we
can revisit this.
Once we support packaging workspaces with dependencies, dependency
packages need to be built before anything is verified. In addition to a
little refactoring, this commit reorders the console messages so that
package metadata (archive size, etc.) is reported before verification
results.

While this is noisy and hides other deprecations, I figured deprecations would
make it easier for people to discover what tasks remain and allow us to
divide and conquer this work rather than doing a heroic PR.
In theory, this will be short lived and we'll go back to seeing
deprecations in our tests.
In `alt_registry::warn_for_unused_fields`, the second part of the test
runs on `--registry crates-io`, so it needs a local replacement url.
In `install::install_global_cargo_config`, it was adding to the "config"
file, but the `pkg` before it configured the dummy registry replacement
in "config.toml". So that replacement wasn't actually used, and if you
ran tests online it was trying to install `bar v0.1.1` from the real
registry! The filename is now fixed, and the test double-checks that
we're only trying to install the local `bar v0.0.1`.
This is to help with #9930
Example changes:
```diff
-[LOCKING] 4 packages
+[LOCKING] 4 packages to latest version
-[LOCKING] 2 packages
+[LOCKING] 2 packages to latest Rust 1.60.0 compatible versions
-[LOCKING] 2 packages
+[LOCKING] 2 packages to earliest versions
```
Benefits
- The package count is of "added" packages and this makes that more
logically clear
- This gives users transparency into what is happening, especially with
- what rust-version is use
- the transition to this feature in the new edition
- whether the planned config was applied or not (as I don't want it to
require an MSRV bump)
- Will make it easier in tests to show what changed
- Provides more motiviation to show this message in `cargo update` and
`cargo install` (that will be explored in a follow up PR)
This does come at the cost of more verbose output but hopefully not too
verbose. This is why I left off other factors, like avoid-dev-deps.
They are still nominally gzipped, but using `Compression::none()` makes
them consistent even across zlib and zlib-ng, and this fixes checksum
differences in the testsuite. There is a one-time update of all those
checksums to catch up with this change though.
fix(metadata): Stabilize id format as PackageIDSpec
### What does this PR try to resolve?
For tools integrating with cargo, `cargo metadata` is the primary interface. Limitations include:
- There isn't an unambiguous way to map a package entry from `cargo metadata` to a parameter to pass to other `cargo` commands. An `id` field exists but it is documented as an opaque string, useful only for comparisons with other `id`s within the document.
- There isn't an unambiguous way of taking user parameters (`--package`) and mapping them to `cargo metadata` entries. `cargo pkgid` could help but it returns a `PackageIdSpec` which doesn't exist within the `cargo metadata` output.
This attempts to solve these problems by switching the `id` field from `PackageId` to `PackageIdSpec` which is a [publicly documented format](https://doc.rust-lang.org/cargo/reference/pkgid-spec.html), can be generated by `cargo pkgid`, and is accepted by most commands via the `--package` flag.
As the `"id"` field is documented as opaque, this technically isn't a breaking change though people could be parsing it.
For `cargo_metadata` they do [use a new type that documents it as opaque but publicly expose the inner `String`](https://docs.rs/cargo_metadata/latest/cargo_metadata/struct.PackageId.html). The `String` wasn't publicly exposed due to a request by users but instead their `PackageId` type replaced using `String`s in the API in oli-obk/cargo_metadata#59 with no indication given as to why the `String` was still exposed. However, you'll note that before that PR, they had `WorkspaceMember` that parsed `PackageId`. This was introduced in oli-obk/cargo_metadata#26 without a motivation given.
**Note that `PackageIdSpec` has multiple representation that might uniquely identify a package and we can return any one of them.**

This was allowed when switching from `toml` v0.5 to `toml_edit` which
started allowing empty keys when parsing TOML.
This mirrors the change
we made for disallowing empty feature names in #12928.
crates.io reads rust-version from the tarball directly, but we can include it in
the publish request for the sake of consistency for third-party registries.
When doing a credential lookup, Cargo deserializes the registry configuration and detects the
registries.crates-io.protocol key as unused and issues a warning.
This fixes the issue by adding the field to the struct
