Reviewed by Jer Noble.

The primary cause for fullscreen to immediately exit was a typo in the use of the PLATFORM
macro which caused requestHideAndExitFullscreen() to be immediately called once we had entered
fullscreen.
Then we had two issues that were revealed once the primary issue was fixed. When running in
iOS compatibility mode, once we entered fullscreen we would either remove the player from the
video layer (CRABS) or teardown the video layer (MSE).
To avoid this, we check if a FigVideoTargetRef is set, which indicate that the application
isn't running in iOS compatibility mode and a LMK isn't in use.

Manually tested MSE and CRABS, for both app in both native (Safari) and compatibility mode (Firefox)

exit fullscreen as soon as we entered fullscreen.
