Steven Wu a9aa57ee0b Reapply "[DependencyScan] Correct setup clang VFS for dependency scanning" ...

This reverts commit e60ae24052 and fix
non-deterministic failures introduced by the commit.

Fix two issues when attempting to testing parallel scanning using
`swift-scan-test` tools:
* Make sure the BumpPtrAllocator in ScanningService is thread-safe so
  there are no race condition when a new slab is allocated.
* Make sure the output of `swift-scan-test` only written from one
  thread. This prevents some race conditions when writing to the same
  raw_fd_ostream.
