android: capabilities: Make keys list into set and member variable

We need to be able to add additional characteristics/request/result keys
into the corresponding list in the static metadata based on libcamera
camera capabilities. We also need to be able to easily check if the
lists have specific keys, for populating templates and result metadata.

Turn the characteristics, requests, and results keys vectors into sets,
and move them to member variables to achieve this.
