Subject: Load model textures checkpoint.

Refactors some Vulkan items related to CompGrBinds and EntityTypes.
Adds some Vulkan globals related to textures.

Adds a number of placeholder items:
- Iffy use of setting Vulkan globals on instanced structs.
- Unimplemented and inaccurate shaders
- Iffy gltf sub-buffer logic (ignores vertex color data)
- MipMap TODOs
- TextureArray TODOs
