Initial Process and Binder support, with CTS.

The Ravenwood environment doesn't support IPC, but much of the code
that developers intend to test (such as AIDL stubs) still relies on
baseline same-process behavior to be intact.

This change adds UID and PID support to Process and Binder, but we
carefully communicate that it's only available when the test author
has configured it via a RavenwoodRule.  This ensures that tests
don't accidentally rely on unexpected defaults, as some tests will
want AID_SYSTEM, and others want a normal app UID.

Also bring along SystemClock, PatternMatcher, and ParcelUuid
along with relevant tests.

Finally, now that we have an IgnoreUnderRavenwood annotation, we
can pivot back our default failure to be a RuntimeException instead
of an AssumptionViolatedException.
