android: camera_metadata: Add functions for instrumenting resizing

Browse source 
Add utility functions to CameraMetadata to check if it has been resized,
and for outputting the actual entry and data count. This is meant to be
used to output information on resizing, to assist developers in
choosing proper initial sizes to avoid resizing. Also make CameraDevice
use these functions for static and result metadata.
