Rollup merge of #63342 - ehuss:remap-path-dep-info, r=alexcrichton
Don't use remap-path-prefix in dep-info files.

This changes it so that dep-info files do not use remapped paths.

Having remapped paths causes problems with Cargo because if you remap to a nonexistent path (like `/rustc/$HASH` which rustc distributions do), then Cargo's change tracking thinks the files don't exist and will always rebuild.

I don't actually know if this is a good idea. I think it makes sense, but I do not know what the exact requirements are for reproducible builds. I consider these files separate from the binary artifacts generated, and as a build-system helper, so it seems reasonable to me.

I'm also not sure if this needs a test. I'll definitely add one on the cargo side if this is merged.

Closes #63329
