Auto merge of rust-lang#112267 - lqd:win-1cgu, r=<try>

Build `rustc` with 1CGU on `x86_64-pc-windows-msvc`

Part of the sanity checks for building rustc with 1CGU everywhere:
- if the `dist-x86_64-msvc` builder doesn't timeout
- how the resulting artifacts perform on `x86_64-pc-windows-msvc`

r? `@ghost`
