st-texture-cache: Save cairo surfaces to a different map

Browse Source 
The default keyed_surface is meant to handle CoglTextures thus we can't
add cairo surfaces to it, as the DestroyNotify function won't handle them.

Then the quicker way is to just add another Hash table for handling
such types of textures, with proper destroy function.
