Midgard aggregates a large amount of state into its renderer state descriptor.
Our current dirty tracking reflects this, with a single RENDERER dirty flag.
That won't work well on Valhall, which splits out orthogonal state into
independent descriptors (a blend descriptor, a depth/stencil descriptor, and so
on). To prepare for Valhall support, this patch moves the driver to finer dirty
tracking.
