Make UnionFileSystem accept all paths Bazel can throw at it.
Instead of relying on a character-by-character StringTrie, segment paths based on PathFragments. This means UnionFS can accept any path that Bazel stores internally, removing the ASCII limitations.
This also means removing the ability to have a filesystem bound for sub-PathFragments, /foo/barbar, /foo/barqux could have the same filesystem bound at /foo/bar. This feature was tested for when a use case was envisioned, but it was never used, so removing it is safe.
RELNOTES: None.
