If a user attempts to run Panfrost on an unsupported GPU (e.g. Mali
T604), Panfrost will refuse to load and will destroy the screen
immediately, allowing for a graceful fallback to a software rasterizer.
However, the screen destroy code calls a screen_destroy function in the
GenXML vtbl -- and this function is still NULL when the allowlist is
checked. This manifests as crashes on unsuported GPUs.
Issue tracked down with Icecream95's mad Ghidra skills.

This commit does several things:
* Unify code common to several drivers by evaluating INTEL_NO_HW within
intel_get_device_info_from_fd (suggested by Jordan).
* For drivers that keep a copy of the intel_device_info struct, a
separate copy of the no_hw field is now unnecessary. Remove them.
* Minimize kernel queries when INTEL_NO_HW is true. This is done for
code simplification, but we may find reason to undo this later on.

This is a presumed erratum workaround. Fixes INSTR_INVALID_PC faults on
some draw_buffers_indexed.* cases on Midgard, where a blend shader is
required to pack RT n > 0.
Backport the workaround from the GL driver. The helper is now in common
code for panvk to use as well; it has the same bug.

When freeing a buffer, we may return a non-idle buffer to the cache,
which means we cannot unmap aux entries at that time. Instead, we
defer unmapping the stale aux entry until we reuse a BO from the cache.
Unfortunately, this can lead to a recursive locking issue:
1. intel_aux_map_add_mapping wants to set up a new aux entry
It takes the intel_aux_map_context::mutex lock, then calls:
add_mapping -> get_aux_entry -> add_sub_table -> add_buffer ->
intel_aux_map_buffer_alloc -> iris_bo_alloc
2. iris_bo_alloc tries to allocate a BO from the cache, doing:
alloc_bo_from_cache -> intel_aux_map_unmap_range ->
intel_aux_unmap_range
...which then tries to take the intel_aux_map_context::mutex lock.
But it is already locked.
One solution would be to rework the aux map handling code to allocate
BOs without holding its lock, but that looks to be painful. Another
is to make the lock recursive, but we try and avoid that. A third
option wuold be to add a BO_ALLOC flag that makes alloc_bo_from_cache
skip any buffers with aux_map_address != 0 so we don't have to unmap,
making the less cache effective but fixing the recursive lock.
A fourth option is to simply bypass the BO cache altogether for the
buffers that hold the aux map itself. Allocating new BOs for the aux
tables should be relatively rare, so there's probably not a lot of
benefit in using the BO cache.

With hw devices, when you submit a present, implicit sync will
make sure the work submitted to the gpu on the client will end
up happening before the present work submitted on the server.
However with sw paths there is no real GPU, the lavapipe fake
GPU thread is client side only and presenting is done directly
from the pixmap (or later shared pixmap). In order for this to
make sense the wsi common code should wait for the fence on the
image before queueing the submit to the server so that all
client works has been flushed to the pixmap before the copy or
present operation is submitted.

When rasterizing legacy-lines, OpenGL defines the width as being an
extrusion along the minor axis, repeating varyings. While the spec
*does* allow for an alternative method that matches our current results,
the OpenGL ES CTS doesn't allow these results even if OpenGL ES has the
same wording of an alternative method.
This is technically speaking a bug in the OpenGL ES CTS, but it seems
like nobody else is using the alternative formulation, at least not
while passing the OpenGL ES CTS. On top of this, the OpenGL specification
explicitly lists the extrusion results as the preferred method.
So it seems like a good idea for us to do this the way the OpenGL
specification prefers regardless; it's going to give less surprising
results to applications, and it's helping us pass some tests.
This math to set these up would "trivially" be:
dx = (dx * dx + dy * dy) / dx
dy = 0
and:
dy = (dx * dx + dy * dy) / dy
dx = 0
...but since we've already calculated dxdy, we can reformulate this to
save a division.
This fixes the following dEQP test-cases:
- dEQP-GLES2.functional.rasterization.interpolation.basic.line_loop_wide
- dEQP-GLES2.functional.rasterization.interpolation.basic.line_strip_wide
