vulkan: add support for regular descriptor pools

This permits:
 - The use of Vulkan filtering on many more devices
 - Better debugging due to lack of descriptor buffer support in layers

Much of the changes here are due to a requirement that updates to
descriptors must happen between the command buffer being waited on,
and the pipeline not being bound.

We routinely did it the other way around, by updating only after
we bind the pipeline.
