Array Transforms public API and parsing

This includes the new FIRFieldValue sentinels, the FSTUserDataConverter code to parse them into internal ArrayTransform operations for use in an FSTTransformMutation, and some sanity testing in FSTMutationTests.

I still need to implement FSTTransformMutation support for local application and serialization (and then integration tests).
