  [clang] Make explicitly-built modules independent of the CWD (#164840)

PR https://github.com/llvm/llvm-project/pull/150123 changed how we
normalize the modules cache path. Unfortunately, empty path would get
normalized to the current working directory. This means that even
explicitly-built PCMs that don't rely on the CWD now embed it, leading
to surprising behavior. This PR fixes that by normalizing an empty
modules cache path to an empty string.
