Carlos Garnacho 9e10d2fa88 cogl: Drop "volatile" from static GTypes in manual registration
As documented in g_once_init_enter(): "While @location has a volatile qualifier,
this is a historical artifact and the pointer passed to it should not be
volatile.". And effectively this now warns with modern glibc.

Drop the "volatile" qualifier from these static variables as it's expected.
