Verify create_descriptor_set calls

[aclysma]

The API takes two inputs:

• the descriptor set layout, created at runtime (possibly by loading an asset)
• an auto-generated struct that's based on reflected shader data

These two parameters should be compatible, but there's no checking to ensure this. At debug time, we should consider validating the two match. This might be possible by hashing (maybe per-shader-type, i.e. just hash frag params and vertex params) or just do a full metadata compare. This can be at debug-time only.
