main: Add test initialization function

Browse Source 
Since Clutter's backend relies on MetaBackend now, initialzation has
to go through meta_init(), both in mutter and in gnome-shell.

However the compositor enum and backend gtype used to enforce the
environment used for tests are private, so instead expose a test
initialization function that can be used from both mutter and
gnome-shell.
