Camera: Add support for new camera zoom API

- Add NDK API spec for the new zoom API
The new zoom API combines optical and digital zoom, and supports both
zoom-out and zoom-in with more precision.
- Add new NDK API to specify separate zoom ratio ranges for different
bokeh modes.
- Add ZoomRatioMapper in camera service to convert between
control.zoomRation to and from scaler.cropRegion.

Test: Camera CTS/ITS/CtsVerifier/ZoomRatioTest
