The Early-Z optimization is disabled when there is a discard
instruction in the shader used in the draw call.
But if discard is the only reason to disable Early-Z, and at
draw call time the updates in the draw call are disabled we
can enable Early-Z using a shader variant.
If there are occlussion queries active we also need to disable
Early-z optimization.
So this patch enables Early-Z in this scenario.
The performance improvement is significant when running gfxbench
benchmark showing an average improvement of 11.15%

FORCE_KERNEL_TAG allows testing kernel uprevs without rebuilding
containers by supplying an external kernel directly for booting on
hardware devices. Renaming it to EXTERNAL_KERNEL_TAG clarifies its
purpose, distinguishing it from KERNEL_TAG which rebuilds containers.

The code seems to assume that it's supposed to be a base index for the
binding array, but it's not. It's entirely meaningless and happens to be
set to 0 for all descriptor types except for input attachments, which is
the one case where it's already ignored. Delete the dead code so that
when we change it to a "no index" sentinel value v3dv doesn't blow up.

Now that build-piglit.sh is no longer removing ‘include_test.h’
this test `program@build@include-directories` is passing which is causing
jobs to fail due to this unexpected improvement. Remove this test from
expected fails so that the jobs can pass.

Instead of trying to match device compatible strings like 'brcm,2712-v3d',
which may change with product revisions, match the device name, like 'v3d'.
This simplifies a bit the matching logic and allows us to have less
diverging paths for hardware and simulator.

This was added only to report the DRM device ID of the actual
GPU used in the simulated environment but there is no real
reason we need to do that, so let's juts keep it simple and
provide the device ID of the simulated device instead.

Since the last changes for EGL_EXT_device_drm_render_node, the
can_present_on_device callback now may receive the render device.
With that, the v3dv implementation may return that this device cannot
be used for presentation.
In particular, this callback is used for x11 wsi, and when through
XWayland it does now get the render device. On x11 wsi, this makes the
swapchain operate on blit mode. The blit mode introduces additional
unneeded overhead on wsi and runs through a different path which
currently causes rendering issues (in particular also with Zink).
Allowing both devices to match in the callback returns all wsi to
operate on the native mode and fixes the issues above.

The results show a reduction in register pressure, but an increase in
spills, which looks contradictory. This is because for some reason, this
optimization makes the NIR scheduler produce code for some shaders in Godot
that cause additional spilling, but the problem seems to be exclusive to
Godot shaders and not really related to the optimization itself but to
how the NIR scheduler works. Excluding Godot shaders we actually see a
decrease in spills and a slightly larger improvement in instruction
counts:
