Auto merge of #41508 - michaelwoerister:generic-path-remapping, r=alexcrichton
Implement a file-path remapping feature in support of debuginfo and reproducible builds

This PR adds the `-Zremap-path-prefix-from`/`-Zremap-path-prefix-to` commandline option pair and is a more general implementation of #41419. As opposed to the previous attempt, this implementation should enable reproducible builds regardless of the working directory of the compiler.

This implementation of the feature is more general in the sense that the re-mapping will affect *all* paths the compiler emits, including the ones in error messages.
