gthread: introduce g_once_init_{enter,leave}_pointer

Browse Source 
These functions can be used to initalize pointer-type variables rather
than a gsize. This is required to support CHERI-enabled platforms where
gsize cannot be used to store pointers. Follow-up changes will migrate
the uses of g_once_init that store pointers to the new API
