GSIZE_TO_POINTER(): appease stricter compilers

Browse Source 
Some compilers (e.g. CHERI LLVM) warn when casting a non-intptr_t integer
type to a pointer. The GSIZE_TO_POINTER() macro thus triggers warnings
which can be silence by casting to guintptr before gpointer.

NB: This macro must not be used to create valid pointers from a integer.
