tests: Adds a really simple cogl-info program

Browse Source 
It could be nice to extend this as Cogl gains more APIs for
introspecting its own features but for now cogl-info just uses the new
cogl_foreach_feature() API to enumerate the available features for
a default context and prints those to the terminal.
