anv/pipeline: Put actual pointers in anv_shader_bin

Browse Source 
While we can simply calculate offsets to get to things such as the
prog_data and the key, it's much more user-friendly if there are just
pointers.  Also, it's a bit more fool-proof.

While we're at it, we rework the pipeline cache API to use the
brw_stage_prog_data type directly.
