core: Define intptr_t variants of wcore_attrib_list functions

When designing the original Waffle 1.0 API, I made a mistake when
I chose to declare attribute lists as arrays of int32_t. Instead, they
should have been arrays of intptr_t.

A new public function, waffle_window_create2, will have a `const
intptr_t attrib_list[]` parameter. Therefore waffle needs intptr_t
variants of the wcore_attrib_list functions.
