Extension header: amend const correctness of `p_args` parameters

A while ago, argument arrays were passed as const GDNativeTypePtr* (void* const*)
This was changed to GDNativeConstTypePtr* (void const**), adding const on the value but removing it on the pointer level.
This commit changes argument types to const GDExtensionConstTypePtr* (void const* const*).

Besides object pointers, the same change is applied to variant pointers.
