pan/midgard: Introduce quirks checks

Rather than open-coding checks on gpu_id in the compiler, let's track quirks applying to whatever we're compiling for, to allow us to manage the complexity of many heterogenous GPUs in the compiler.

It was discovered that a workaround used on T720 is also required on T820 (and presumably T830), so let's fix this. This will also decrease friction as we continue improving T720 support (will use for LOD clamps).
