evas/cserve2: Implement support for GL engine

Simply call the appropriate cache2 functions when possible
and check for usage of cache2 whenever an evas_cache_ function
is called.

This effectively adds cserve2 image (data) load support for the
GL engines. Fonts were already working out-of-the-box.
