camera: Add a hwlevel attribute, annotate each metadata's hardware level
* Set each metadata key to one of full,legacy,limited.
* All keys present on the lower level must also be present on higher
levels (i.e. all legacy keys present on limited/full devices, all limited
keys present on full devices.)
* If a key is not annotated, it is assumed to be optional even on full.
This is usually the case only for future, deprecated, or system keys.
