SkColorType instead of (deprecated) SkBitmap::Config

Part of this refactoring was the recognition of a common pattern:
- setConfig + alloc + setImmutable + pass_to_UIResourceBitmap

This CL introduces a direct way on UIResourceBitmap to create such a bitmap, by just specifying its dimensions. This encapsulates internal requirements (e.g. colortype and immutability).
