py: Generate control enums from yaml

Generate enums for controls from control_ids.yaml. The generator script
has some heuristics to generate nicer enum names. E.g. instead of having
"LensShadingMapMode.LensShadingMapModeOff" we get
"LensShadingMapMode.Off". This heuristics may need to be updated when
the yaml file is changed or new controls are added.
