Camera2: Protect MarshalRegistry against concurrent access
Multiple CameraMetadataNative objects could be reading and writing
to the metadata marshaler registry simultaneously.
This can lead to an infinite loop in the HashMap in the worst case,
so add synchronization against this.

camera2: Performance potpourri.
Bug: 16208403
Bug: 15116722
Fixes many of the performance issues in the Camera2 API and
LEGACY mode CPU path, including:
- Only call getParameters/setParameters when the request has changed.
- Cache Request/Result objects.
- Cache object hashes for long-lived CameraMetadata, TypeReference,
and Key objects with frequently used hash methods.
- Switch to Command pattern instead of repeated if/equals calls.
in frequently hit CameraMetadata get/set methods.
- Move string construction for logging behind flags to avoid extra
StringBuilder calls in frequently acquired lock methods.
- Cache results from frequently used JNI calls in object Builders.

camera2: Update native<->managed camera metadata marshalers
* Improve existing marshalers:
- each managed/native type combination can be queried marshal support
- marshalers can recursively call other marshalers for nested types
- support marshaling/unmarshaling generic classes by using super type tokens
* Add new marshalers for:
- ColorSpaceTransform
- MeteringRectangle
- Parcelable
- Range<T>
- ReprocessFormatsMap
- RggbChannelVector
- SizeF
- StreamConfiguration
- StreamConfigurationDuration
Batteries included; so are unit tests.
