This introduces a new blorp_copy() path using the new XY_BLOCK_COPY_BLT
blitter command introduced on Tigerlake. Unlike the blitter commands of
old, this one is actually fast and worth using. Although it doesn't use
shaders like the rest of BLORP, we still can use some surface-munging
code from there, and BLORP also provides a nice place to put this which
is shared among the drivers.
To use the new path, set BLORP_BATCH_USE_BLITTER (much like Jordan's
recent BLORP_BATCH_USE_COMPUTE bit) and target the batch at the copy
engine.

We don't support typed image writes for multisampling, so we can't
handle multisampled destinations. We also usually handle MSAA by
running the fragment shader per-sample, which we aren't accounting
for in our compute shaders, so we can't handle MSAA sources either.
We could do both of these things if we really wanted to, but we don't.

When we're doing a stencil blit via a fragment shader, we can avoid
W-tiling shenanigans by using the stencil write hardware on Skylake
and later.
Of course, the compute engine doesn't have stencil fragment writes,
so it can't do that. Just fall back to the detiling shenanigans.

When dispatching compute shaders to do a blit, our destination rectangle
may not line up perfectly with the workgroup size. For example, we may
round the left x0 coordinate down to a multiple of the workgroup width,
and the right x1 coordinate up to the next multiple of the workgroup
width. Similarly for y0/y1 and workgroup height. This means that we
may dispatch additional invocations which should not actually do any
blitting. We need to set key->uses_kill to bounds check and drop those.

This is mostly a bit of future-proofing. We never end up with offsets
that don't fit in 32 bits today because, thanks to driver limitations
caused by relocations, we don't allocate buffers bigger than 2GB today.
However, if we ever did, it's possible to create a surface on modern
platforms that consumes more than 4GB and we would end up with wrapping
in our offset calculations.

Upon looking at caching the raytracing shader (in particular the
trampoline one) I kind of got afraid that some of the keys used for
blorp would end up matching other keys. This is because blorp keys are
fairly simple. There is no SPIRV module hash included.
This change includes a "blorp" string at the beginning of the queue to
ensure we don't collide with other keys.

integers. That is causing problems with the Vulkan API where we need
to be able to use a 3D layer that could be in between 2 layers.

internally sets up the input parameters to pass floating point values
