Add Ogg Theora support to MovieWriter

Movie Maker mode can now record files in `.ogv` format, which can be
directly viewed in Godot's VideoStreamPlayer node along with most
video players. This is a lossy format with inter-frame compression,
unlike AVI + MJPEG which only performs intra-frame compression.
