Merge "camera: Clarify docs for ICameraDeviceSession.repeatingRequestEnd()" into main

     * This can be called at any point after 'processCaptureRequest' in response

     * to camera clients disabling an active repeating request.

     *

     * Note: The frame number parameter is the latest possible frame number at which the

     * ongoing repeating request will end. It is possible that the repeating request may end

     * before the specified frame number due to reasons such as the camera client abandoning

     * buffers, which is timing dependent.

     *

     * Performance requirements:

     * The call must not be blocked for extensive periods and should be extremely lightweight. There

     * must be no frame rate degradation or frame jitter introduced.
