anv: Include the pipeline layout in the shader hash

The pipeline layout affects shader compilation because it is what
determines binding table locations as well as whether or not a particular
buffer has dynamic offsets.  Since this affects the generated shader, it
needs to be in the hash.  This fixes a bunch of CTS tests now that the CTS
is using a pipeline cache.
