Rollup merge of #108865 - Zoxc:library-dummy-crate, r=jyn514

Add a `sysroot` crate to represent the standard library crates

This adds a dummy crate named `sysroot` to represent the standard library target instead of using the `test` crate. This allows the removal of `proc_macro` as a dependency of `test` allowing these 2 crates to build in parallel saving around 9 seconds locally.
