pan/midgard: Turn Z/S stores into zs_output_pan intrinsics

Browse Source 
Midgard can't write depth and stencil separately. It has to happen in
a single store operation containing both. Let's add a panfrost specific
intrinsic and turn all depth/stencil stores into a packed depth+stencil
one.

Note that this intrinsic is not yet handled in emit_intrinsic(), but
we'll address that later.
