Implement session param injection in CameraService
- This allows injecting session params into existing camera clients.
- The injection is cleared upon the camera closing, and we do not keep
state from one camera open to the next.
- We restrict the injection to only allow overriding vendor tags for now.
- The actionable parts of the change are gated behind the inject_session_params
flag to allow easy flipping. When false, this feature will have no effect.
Bug: 308984721
Test: I tested that this works using adb shell.
