GType: introduce GTYPE_TO_POINTER/GPOINTER_TO_TYPE

Browse Source 
On CHERI-enabled systems we use uintptr_t as the underlying storage for
GType and therefore casting to gsize strips the upper bits from a pointer.
Fix this by casting via uintptr_t instead and introduce a new set of
macros to convert between GType and pointers.
