Split AttachmentStateDescriptor, in order to match web idl

Browse Source 
AttachmentStateDescriptor was removed in web idl. Its format info
for color attachment and depth/stencil attachment were split and
added into BlendStateDescriptor (renamed to ColorStateDescriptor)
and DepthStencilStateDescriptor (became optional) respectively.

This change makes dawn project match the revision in web idl.
