The rustc, rustdoc, rustc_wrapper, and rustc_workspace_wrapper config values (in the [build] table) were being interpreted literally. This caused a problem if you used a relative path like foo/rustc. This would be interpreted as a relative path from whatever cwd cargo launches rustc from, which changes for different scenarios, making it essentially unusuable (since crates.io dependencies wouldn't be buildable).

Additionally, due to rust-lang/rust#37868, it is a bad idea to use relative paths.

This changes it so that those paths are config-relative. Bare names (like "my-rustc-program") still use PATH as before.

This also includes a commit to centralize the rustc-wrapper program used by several tests so that it isn't built multiple times (and to allow several tests to work on windows).

Fixes #8202
