Format: Move the baseType to be per-aspect.

Browse Source 
This also introduces a per-aspect supportedComponentTypes that exactly
mirrors baseType for now but will contain additional bits in the future
(like DepthComparison for depth textures).

It is also a step towards being able to create single-aspect view of
depth-stencil textures to sample either the depth or the stencil
component.
