intel/blorp: Add the BDW+ optimized HZ_OP sequence to BLORP

We'll be switching to layout-transition based resolves which can occur
outside of a render pass. Add this sequence to BLORP, as using BLORP
will enable emitting depth stencil state outside of a render pass (among
other benefits). The depth buffer extent is ignored to enable eventual
usage in VkCmdClearAttachments().
