Add workaround for broken vendor camera on/off requests.

Scenario: A and B are in video call.
A goes to the background, pausing the video.
B attempts to turn off their camera.
The request fails to be interpreted by vendor code.

Reason: This SHOULD really be a request to go from/to:
Audio/TX/RX/Paused --> Audio/RX/Paused
However, it MUST be sent as:
Audio/TX/RX/Paused --> Audio/RX

The introduction of the VideoPauseTracker in N caused the request to be
sent in the former correct format rather than the latter incorrect format.

The VideoPauseTracker attempts to ensure that a request to pause sent by
the framework vs the incall ui are kept in sync (we use pause to disable
video on a call when the data limit is reached).  In the process of ensuring
pause and resume requests were handled properly, this code was
fixing the malformed request.

Added a workaround to the code to ensure the requests remain in the same
broken format vendor code depends on.

Test: Manual, unit
