Normally Venus on Nvidia GPUs takes the prime blit path. The exception
is when KWin or any wlroots based compositors are used:
1. KWin and wlroots based compositors always add LINEAR to dmabuf
feedback tranches assuming LINEAR can be handled by GPU drivers.
2. Venus + Virgl only sees the compositor injected LINEAR mod since
Virgl doesn't support explicit modifiers on the driver side.
3. Nvidia GPUs doesn't support LINEAR color attachment, and it's too
late to reject LINEAR mod when the native image path has already
been taken instead of the prime image path.
Gamescope requires VK_EXT_physical_device_drm and its runtime doesn't
use standard WSI extensions, so venus can spoof without impacting it.

No issue with clang or gcc-14.x (or earlier versions). The issue only
shows up since gcc-15.1. The compiler somehow fails to consider those
cs helpers dereferencing the pointer from the pNext chain for reads,
and thus has falsely optimized away the pNext store. This change works
around this with a no-op memory clobber.

If descriptor heap is used, there's no pipeline layout created. So we
have to patch compute and RT pipelines to allow it. Graphics pipeline
doesn't need the change because of GPL.

There're potential optimizations available for below:
- vkWriteSamplerDescriptorsEXT
- vkWriteResourceDescriptorsEXT
- vkGetPhysicalDeviceDescriptorSizeEXT
- vkRegisterCustomBorderColorEXT
...and we can revisit if there's perf hit from above for real apps.

Those have long been supported by vn_image_deferred_info_init because of
AHB support. For non-aliased ANB image, those are directly passed from
the platform swapchain create info as well. So we just need to drop the
obsolete asserts to make newer Android platform and ANGLE happy.

WSI used to track the similar for aliased wsi image creation, but later
got deprecated. So let's rename wsi.memory to wsi.anb_mem and drop
wsi.memory_owned to avoid confusions with common wsi related trackings.

Vulkan is supposed to operate in explicit synchronization mode. However,
for legacy compositors that only support implicit fencing, we have to
extract the compositor implicit fence (release fence) and resolve it
properly.
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/39401>
Previously common wsi has a special submission to install implicit fence
to wsi memory directly, which has been deprecated in favor of bonfire
implicit fencing (implicit fencing has been turned into explicit fencing
within vulkan since then). The virtgpu backend is fine but the vtest
backend has been regressed since then, only relying on renderer side hw
driver doing implicit fencing.
With async present landed earlier, we can directly tell which submission
is done by common wsi, and can revive the idle waiting accordingly.

ANV can return different memory requirements with and w/o the ALIAS bit.
See https://gitlab.freedesktop.org/mesa/mesa/-/issues/14671 for details.
Meanwhile, venus has a driver side cache for image memory requirements.
As blessed per spec for memory aliasing, venus strips the ALIAS bit when
populating the cache key. Because of the use of imageless mem req query,
the ALIAS mem req now can hit the cache first, leaving a smaller/relaxed
requirement in the cache...busted.
Venus is unable to fix ANV behavior behind the scene, so this workaround
is only to align Venus behavior with ANV to not suffer from Venus-only
rendering artifacts.

As mentioned in earlier commit, for sem fd export on async present
thread, it occurs after internal queue submissions for all swapchains.
So we can allow queue commands while sync wait w/o violating ordering.

For sem fd export on async present thread, it occurs after internal
queue submissions for all swapchains and before presenting to WSI
backend. We can safely unlock the chain acquire lock though we still
have to lock against chain destroy as well as chain async present on
other queues.
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/39283>
Brief:
1. present info is deep-copied and passed to async present thread
2. normal queue present always waits for async present to take over
3. queue access is protected by async present queue lock
4. chain access is protected by chain locks
5. no perf gain in practice since we haven't allowed parallel queue
submit or acquire image yet
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/39283>
During async presentation, swapchain is accessed by the async present
thread. With proper queue and chain access locks within venus driver,
we still have to rely on mesa common wsi implementation specifics for
optimal async present performance:
Below need to be protected:
- vkAcquireNextImage2KHR
- vkDestroySwapchainKHR
Below are safe:
- vkGetSwapchainImagesKHR
- vkWaitForPresentKHR
- vkWaitForPresent2KHR
- vkReleaseSwapchainImagesKHR
- VkSwapchainPresentFenceInfoKHR::pFences
