jp9000 8f43934be6 UI: Lock graphics context when adding new sources ...

Prevents a potential cross-lock deadlock.  The UI thread would lock the
scene's mutex in obs_scene_atomic_update, then the item would lock the
graphics context to create a texture.  Meanwhile in the video thread, it
could lock the graphics context in the render loop, then lock the
scene's mutex when rendering.  When doing anything graphics-related, the
graphics context is always supposed to be locked before the scene's
mutex is supposed to be locked (it's designed that way), and the
obs_scene_atomic_update would just bypass that.
