Camera: expose external camera to API1

- Cleanup legacy camera_module_t callbacks
- Order API1 compatible cameras by their ID: numeric strings first
- Dynamically updating number of cameras when device is
  added/removed
- Make sure the following methods are always called without holding
  mServiceLock
    - onDeviceStatusChange
    - updateStatus
    - addStates/removeStates
- Centralized all addState/removeState calls in onDeviceStatusChange
- Passing api1CameraId (number) and cameraDeviceId (string) to various
  client classes.
- Allow FOV information to not present for external camera
- Update API1 preview/video size logic to exclude < ~30fps sizes
