Xe KMD only requires userptr to be bound to VM, so here reusing
workaround_bo->gem_handle id to all userptr bos in Xe version of
gem_create_userptr(). The Xe version of gem_close() will make sure
that workaround_bo->gem_handle is not closed when userptr bos
are closed.
With the same gem_handle for all userptr bos, it was also necessary
skip the anv_device_lookup_bo() and manually allocate memory to store
anv_bo in host heap memory, what lead to some small changes in
anv_device_release_bo() as well.
The remaining changes are the support to VM bind userptr bos and the
gem_vm_bind() call in anv_device_import_bo_from_host_ptr().

Wa_14016118574 is not the lineage number for this workaround so
it was updated to Wa_22014412737.
Wa_22014412737 is not applicable for MTL B0 steppings and newer
so using the workaround framework eliminates this pipe_control
instruction for not affected revisions.

It turns out the hardware doesn't save the whole state on a context
switch, as the kernel expects when it creates the golden context.
For some HW units, only the state that was explicitly programmed will be
part of it, so we need to make sure mesh shading is disabled on context
creation, or we risk being context switched with an application that
uses mesh, and when ours gets to run again, the mesh state won't be
reset, and submitting a legacy 3D pipeline while the HW thinks mesh is
enabled causes us to hang.

utrace submits can either have a batch or not.
When there is a batch, the utrace vk_sync is signaled by the utrace
batch (because utrace does a timestamp buffer copy using its own
batch). When there is no batch, the utrace vk_sync should be signaled
by the application batch (no timestamp copy required, utrace can read
the timestamps when the application batch has completed).

anv_vma_alloc() returns a canonical address, but explicit_address is a
regular address. This mismatch can potentially cause issues.
So here making bo->offset as always canonical address by converting it
in the explicit case and fixing the only caller that was caling
anv_bo_vma_alloc_or_close() with a canonical address.

The Vulkan specification indicates that if memory types have
properties which are a strict subset of another type's, then they
should appear before that memory type. Otherwise the specification
does not require a specific ordering of memory types.
But, it appears that Aztec Ruins and the Vulkan CTS make an assumption
that the first host-accessible memory type is host-coherent and select
it when they expect data written by the CPU to become visible without
calling vkFlushMappedMemoryRanges(), even though flushing is required
by the spec, which leads to misrendering and hangs on MTL platforms.
We found that other drivers also put a host-coherent, but not cached
memory type as the first host-accessible memory type, so let's do the
same in order to match the expectations of such broken applications.
Host-coherent uncached memory types are currently implemented with a
WC CPU map on non-LLC platforms, so there shouldn't be a huge
performance penalty from this: If an application intends to do heavy
R/W CPU access on a memory range it's expected to loop over the
available memory types and select one marked as host-cached -- If an
application fails to do that and simply selects the first available
type it seems more robust to stay on the safe side and give them a
host-coherent type rather than a cached one.

Although the following is based on this observations for OpenGL, we
probably need this for Vulkan as well.
KHR-GL46.texture_buffer.texture_buffer_operations_ssbo_writes writes
to an SSBO in a compute program, then issues a memory-barrier, which
causes us to add a DC-flush. Then a second compute program samples
from the SSBO written by the first compute program.
Although we expected the DC-flush to make the writes available to the
second compute program, on MTL this wasn't the case. Adding the
"Untyped Data-Port Cache Flush" fixes this.
The PRM indicates that compute programs must set "Untyped Data-Port
Cache Flush" to flush some LSC writes when flushing HDC. Although we
are setting DC-flush, and not HDC-flush, it does appear that the
following reference might also apply to DC-flush.

On Alchemist, the FF_MODE2 documentation says that we must set the
FF_MODE2 timer values for GS and HS to 224. The hardware performance
tuning guide also recommends setting the TDS timer to 4.
On Tigerlake, i915 applies workarounds to set the GS timer to 224
(failing to do so can cause HS/DS unit hangs), and the TDS timer to 4
(for performance). It doesn't currently apply a HS timer there, and
I'm not sure if it's strictly necessary, but given that Alchemist
needed it, and the other two settings matched, let's assume that it
ought to match as well.
Unfortunately, there has been a bug in the i915 workarounds
infrastructure for non-masked context registers where writing one
field of the register zeroes out all the others. So, I believe the
Tigerlake TDS timer value of 4 isn't being applied correctly there,
though the register is also not readable on that platform which
makes it hard to verify. So, this may also speed up tessellation.
