Expand description

Remap all paths pointing to `build.build-dir`, i.e., `[BUILD_DIR]/debug/deps/foo-[HASH].dwo` would be remapped to `/cargo/build-dir/debug/deps/foo-[HASH].dwo` (note the `/cargo/build-dir` prefix).

This covers scenarios like:

- Build script generated code. For example, a build script may call `file!` macros, and the associated crate uses `include!` to include the expanded `file!` macro in-place via the `OUT_DIR` environment.
- On Linux, `DW_AT_GNU_dwo_name` that contains paths to split debuginfo files (dwp and dwo).
