Add abstraction for bindless resources

Sorry for the dumb mistakes it was late when I pushed yesterday lol

I wasn't sure how to write a method to bind the pool descriptor set so I did it in the simplest and most direct way. Let me know if won't do.

I'm particularly worried of the fact that ensure_descriptor_state might overwrite the binding because no changes are done to current_descriptor_sets, meaning that binding something at a certain index and then a bindless pool at that index results in the previous thing being bound maybe? If that's the case it might maybe be sufficient to empty the set entry when binding the pool, or maybe tacking pool binds and then doing the actual bind in ensure_descriptor_state like other descriptors.

What I imagine is best is to try to implement pipeline layout compatibility (See the spec). What this means in practice is that when calling ensure_descriptor_state(), if the sets bound to the first 0..N items are the same, we should not update and clear them if bindings 0..N are compatible with the current pipeline layout (this might also require some changes to the bind_pipeline function).

We can then try to include the bound pools in this calculation so they are not cleared when the layout is compatible.
