Revert "Reland [clang] Canonicalize system headers in dependency file when -canonical-prefixes" (#71697)
This reverts commit 578a4716f549167165a2ec3bac89c86706136d4e.

This causes multiple issues. Compile time slowdown due to more path
canonicalization, and weird behavior on Windows.

Will reland under a separate flag `-f[no-]canonical-system-headers` to
match gcc in the future and further limit when it's passed by default.

Fixes #70011.
