feat(resolve): Tell the user the style of resovle done
### What does this PR try to resolve?
This is to help with https://github.com/rust-lang/cargo/issues/9930
Example changes:
```diff
-[LOCKING] 4 packages
+[LOCKING] 4 packages to latest compatible version
-[LOCKING] 2 packages
+[LOCKING] 2 packages to latest Rust 1.60.0 compatible versions
-[LOCKING] 2 packages
+[LOCKING] 2 packages to earliest compatible 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.
### How should we test and review this PR?

feat: Add 'open-namespaces' feature
### What does this PR try to resolve?
This is a step towards #13576
### How should we test and review this PR?
### Additional information
In 12914 we stabilized pkgid spec as unique package identifier for
`cargo metadata`. However, we forgot to make the same change to
JSON message format[^1]. This PR does so.
Note that the `package_id` field in JSON message is not clearly stated
as "opaque", so it might be considered as a breaking change to some extent.

This is an alternative to #12158's `CARGO_WORKSPACE_DIR` that was
implementing the solution to #3946 that previously discussed in the
cargo team meeting.
`CARGO_WORKSPACE_DIR` is a bit awkward to document / describe because
its the effective workspace directory of the thing being built.
If the thing being built doesn't have a workspace, it falls back to
`CARGO_MANIFEST_DIR`.
It would also be hard to take into account what the
`CARGO_WORKSPACE_DIR` would be for path dependencies into foreign
workspaces *and* it wouldn't solve the problem the user is having.
What the user really wants is the CWD of rustc when it is invoked.
This is much simpler to describe and is accurate when using a path
dependency to a foreign package.
Because the CWD is a much simpler mechanism to talk about, I figured we
could diverge from our prior consensus and make it always present,
rather than limiting it to tests.
Remaining work for #3946: get this stabilized
This commit adds support for passing the keyword "default"
to either the CLI "--jobs" argument on the "[build.jobs]"
section of ".cargo/config".
This is dony by:
1. Changing the "jobs" config type to an enum that holds
a String or an Integer(i.e. i32).
2. Matching the enum & casting it to an integer

It was unnecessary to pass `spilt-debuginfo` if there is no debuginfo.
Tests are touched here only for matching rustflags invocation stderr
in the original test suite.
Previously, `Debuginfo::None` meant "don't pass -C debuginfo" and `Explicit(None)` meant
"-C debuginfo=0", which occasionally led to caching bugs where cargo would sometimes pass
`-C debuginfo=0` and sometimes not. There are no such bugs currently that we know of, but
representing them the same within cargo avoids the possibility of the bug popping up again in the
future.
I tested the `with_stderr_does_not_contain_tests` with this diff to ensure they did not pass:
