Change SubresourceRange to be hierarchical.

Initializing SubresourceRange with {x, y, z} type of constructor
was error prone because it was going from the smallest concept
to the larger one instead of being hierarchical.

This CL changes the order of the structure and more importantly
adds a constructor that's in hierarchical order and groups related
members together. For example:

  SubresourceRange range(Aspect::Color, {layerStart, layerCount}, {0, mipCount});

It also adds a rename of SingleMipAndLayer in hierarchical order as
SubresourceRange::Single and a helper that gives a full range as
SubresourceRange::Full (it will be used in follow-up CLs).
