agx: Add block_image_store instruction

Browse Source 
This hw instruction writes out an entire block from the tilebuffer to an
attached render target (PBE descriptor). It is used (only?) in end-of-tile
shaders to implement write out. We need to handle it in the compiler as a
prerequisite to compiling end-of-tile shaders ourselves, instead of hardcoding.
