Josh Triplett a971238175 std_detect: Use rustc-std-workspace-* to pull in compiler-builtins
https://github.com/rust-lang/rust/pull/145489 changed `std_detect` to no
longer depend on `cfg-if`, which meant it no longer indirectly pulled in
`rustc-std-workspace-core` via `cfg-if`. That caused it to no longer
depend on `compiler-builtins`.

Change `std_detect` to use `rustc-std-workspace-core` and
`rustc-std-workspace-alloc`, to integrate with the rustc workspace. This
also pulls in `compiler-builtins` via `rustc-std-workspace-core`.

Closes: https://github.com/rust-lang/rust/issues/145594
