Use SubresourceStorage to track per-subresource state.

Using this container is a small performance regression in the simple
cases where all subresources are the same, or when the texture has few
subrsources. However it give better performance in the hard subresource
tracking cases of textures with many subresources.

Using SubresourceStorage also makes it easier to work with compressed
storage since the compression is mostly transparent. It reduces code
duplication and prevent bugs from appearing when a developer would
forget to handle compression.

This fixes a state tracking issue in ValidatePassResourceUsage where the
function didn't correctly handle the case where the PassResourceUsage
was compressed.

Also removes the unused vulkan::Texture::TransitionFullUsage.

Also makes SubresourceStorage<T> only require operator== on T and not
operator !=.

Also fixes the texture format's aspect being used to create pipeline
barriers instead of the range's aspects.
