This try to mitigate the HiZ GPU hang by increasing a timeout. Loosely
based on PAL but I can confirm it delays the hang when
BOTTOM_OF_PIPE_TS is used as a workaround.
This must be emitted when the GFX queue is idle.

VK_ERROR_INITIALIZATION_FAILED will fail physical device enumeration.
Returning VK_ERROR_INCOMPATIBLE_DRIVER means that the driver can still
be used on supported GPUs when multiple GPUs are installed.

Only small prim culling uses the viewport state, so only that must be

VK_MESA_image_alignment_control is used by vkd3d-proton to set
optimal alignments for images. Though, the preferred alignment was
only applied to the surface (or the stencil aspect) but not to the HiZ
surface due to the NULL check.
This caused rendering issues because swizzle modes didn't match.

This is based on Timur Kristof's code, but there are a lot of differences.
The idea is that it doesn't just compute an intersection between a point
and a triangle. It computes the *distance* between a point and a triangle
and it does so in screen space. It accurately takes the subpixel precision
of the rasterizer into account, so that it works optimally at all
resolutions, all MSAA modes, and all quant modes.
The distance computation is only approximated because it only considers
the infinite lines going through triangle edges. However, it seems to be
more than sufficient in practice because the existing rounding-based small
prim culling compensates for it.
The performance improvement is up to 10% in some geometry-bound tests,
though targeted microbenchmarks can show a lot more than that.

The previous concept was to emit the non-deferred shader part
first, including the culling code, and then modify the
non-deferred part accordingly.
This caused some issues because it was really impossible to tell
which sysvals the deferred part needs after DCE, so we had to
run an additional cleanup pass afterwards.
The new concept is to prepare the deferred part first by applying
reusable variables (from the non-deferred part) and run DCE.
This opens the possibility to accurately gather info about what
the deferred part needs.
This idea is further expanded in the next commits.

At least, NAVI10, NAVI21 and NAVI24 are affected by this what looks
like a hardware bug when primitive restart is changed and no context
registers are written between draws. It seems the hardware doesn't
consider primitive restart at all in this situation.
Adding SQ_NON_EVENT(0) as suggested by Marek seems to fix it reliably
without introducing any overhead. It's basically a NOP packet that adds
a small delay.
Fixes new VKCTS coverage dEQP-VK.transform_feedback.primitive_restart.*.
Also fixes this old vkd3d-proton issue.

We can do W and face culling when we have multiple viewports, but not
frustum and small prim culling because those are dependent on the viewport.
When a shader writes the viewport index, the new option allows skipping
viewport-based culling while keeping W and face culling.
