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().

We're about to start passing other things in as a sort of "VS header" for
vertex shaders and we need a place to put them. Since we want the instance
id to be one of them, it makes sense to have one vec4 that's either VUE
header or VS header. Always uploading some handy zeros makes the code a
bit simpler.

At least on Sky Lake, after emitting 3DSTATE_CONSTANT_*, you are required
to re-emit the 3DSTATE_BINDING_TABLE_POINTERS packet for the corresponding
stage. If you don't, double-buffering may fail and you may get the wrong
constants. It turns out that you need to do this even if you have no push
constants to speak of or else the next 3DSTATE_CONSTANT packet you emit for
that stage may not work correctly.

In Vulkan, we want to be able to use blorp to perform clears inside of a
render pass. If blorp stomps the depth/stencil buffers packets then we'll
have to re-emit them. This gets tricky when secondary command buffers get
involved. Instead, we'll simply guarantee that the depth and stencil
buffers we pass to blorp (if any) match those already set in the hardware.

This never mattered before because the only time we used blorp
depth/stencil only was to do HiZ operations on gen6-7. It may have worked
in that case (and maybe it didn't) but slow depth clears actually do depth
rendering so they need a valid render target.

This should now set the pipeline up properly for doing depth and/or stencil

emitting color calculator state for blorp operations without an actual

The Vulkan driver sets 3DSTATE_DRAWING_RECTANGLE once to MAX_INT x MAX_INT
at the GPU initialization time and never sets it again. The GL driver sets
it every time the framebuffer changes. Originally, blorp set it to the
size of the drawing area but meant we had to set it back in the Vulkan
driver. Instead, we can easily just do that in the GL driver's blorp_exec
implementation and not set it in blorp core.

The original blorp_alloc_binding_table helper was supposed to return the
binding table offset and map along with the surface state maps. This isn't
quite what we want, however. What we really want is the binding table
offsets, surface state offsets, and surface state maps. In the GL driver,
the binding table map *is* an array of surface state offsets. However, in
Vulkan, this isn't quite true as the entries in the binding table are
surface state offsets combined with another binding table block offset.

While it can be useful, the field has substantial limtations. In
particular, the bittom 2 or 3 bits is missing so your offset always has to
be a multiple of 4 or 8. While surface alignments usually work out to make
this ok, when you start trying to fake compressed surfaces as uncompressed
(which we will want to do) this falls apart. The easiest solution is to
simply align all offsets to a tile boundary and munge the regions we're
copying to account for the intratile offset.
