link.exe: Don't embed full path to PDB file in binary. This PR makes `rustc` unconditionally pass `/PDBALTPATH:%_PDB%` to MSVC-style linkers, causing the linker to only embed the filename of the PDB in the binary instead of the full path. This will help implement the [trim-paths RFC](https://github.com/rust-lang/rust/issues/111540) for `*-msvc` targets. Passing `/PDBALTPATH:%_PDB%` to the linker is already done by many projects that need reproducible builds and [debugger's should still be able to find the PDB](https://learn.microsoft.com/cpp/build/reference/pdbpath) if it is in the same directory as the binary. r? `@ghost` Fixes https://github.com/rust-lang/rust/issues/87825
