CI: merge msvc cargo and tools jobs

[Kobzol]

The x86_64-msvc-cargo and x86_64-msvc-tools jobs both run for ~1 hour, but most of that time is actually spent in building LLVM and rustc, so I want to try merging them.

The build has finished in 1 hour 13 minutes, so this would cut the duration of the two jobs approximately in half, when combined. https://github.com/rust-lang/rust/actions/runs/5312775017/jobs/9617766087?pr=112796
