anv: More carefully dirty state in BindPipeline

Browse Source 
Instead of blindly dirtying descriptors and push constants the moment we
see a pipeline change, check to see if it actually changes the bind
layout or push constant layout.  This doubles the runtime performance of
one CPU-limited example running with the Dawn WebGPU implementation when
running on my laptop.

NOTE: This effectively reverts beca63c6c0.  While it was a nice
optimization, it was based on prog_data and we can't do that anymore
once we start allowing the same binding table to be used with multiple
different pipelines.
