cogl/onscreen: Add way to manually add frame infos

Browse Source 
We will soon need to use CoglOnscreen frame events communicate cursor
plane changes; this means we need to have a way to queue them without
going through any of the current APIs that can do so, i.e. the swap
buffer functions and direct scanout.

Add a function that just adds a frame info to the queue. The one who
adds it is responsible for emitting it too.
