[io][vfs] Add new POSIX open flags.

Adds OPEN_FLAG_POSIX_WRITABLE and OPEN_FLAG_POSIX_EXECUTABLE.

Whitelist flag where required, and update VFS implementations to support
both old and new flags.

Notably, the old flag is not expanded to the new flags yet in all
cases due to binary incompatibility. This will be addressed in a
subsequent change when a new SDK and binaries have rolled.

Update Rust tests to ensure whitelisted flag is removed.

Bug: 40862
Tested: Built+Ran. Updated unit tests.
