pan: Add a central libpanfrost_compiler library

The only thing that only pulls in bifrost is our CL compiler for
pre-builts.  Everything that uses pan_shader.h pulls it in because
that's header-only and calls into both back-ends anyway.  Some day
we might want to figure out how to properly dead-code the midgard
compiler for Vulkan but today is not that day.
