Camera: Add adb shell cmd to override stream use case

Adding ability to override stream use cases using adb makes testing
3P apps' stream use case behavior easier. 3P apps don't need to make code
change.

Example:

adb shell cmd media.camera set-stream-use-case-override STILL_CAPTURE \
PREVIEW_VIDEO_STILL
adb shell cmd media.camera clear-stream-use-case-override

Test: Run social media app after set-stream-use-case-override
