Michael Parkin-White 0722bab515 Metal: Optimize SSR shader for Apple Silicon 
Reduce register spill to global memory in raytrace_resolve
function. Results in a 20% uplift for this particular shader on
Apple Silicon GPUs. Contributing to 3-5% uplift for scenes
which have SSR enabled. This is achieved via reducing
memory pressure using a packed data type for the sampling
kernel.
