* Fix some FOV calculation viewport issues:
-Avoid calculating FOV if we've got an invalid viewport
-Don't override game mode FOV, let the active camera components manage it instead
* Fix viewport font positioning
This updates code in a few places to respect an API change/fix made to AtomFont - also switched the default value of m_virtual800x600ScreenSize to false as it's really behavior you want to opt into
* Don't activate CameraComponentController when in the Editor / not in game mode
This ensures the camera entity's transform gets correctly set if the RPI::View (or ViewportContext) is directly used instead of adjusting the entity transform, for e.g. camera controllers.
