Camera2: Update all CTS tests for depth-only devices

It is possible for a device to only support depth outputs; such
devices need to skip most tests that use YUV or JPEG outputs, or the
tests need to be updated to select DEPTH16 sizes instead of YUV.

A few tests are updated to verify other properties of depth-only
devices.
