[Ravenwood] Internal clean up, more PFD APIs, OsConstants, etc

- Support a few more ParcelFileDescriptor APIs.
- Support OsConstants and a couple of Os APIs.

- Also clean up f/b/ravenwood. Now we have "runtime-common" library
  that can be used from different components of Ravenwood infra,
  with native code support.
