gallium/dri2: Fix creation of multi-planar modifier images

The commit noted below assumed and enforced that DRM_MOD_INVALID was the
only valid modifier for multi-planar imported images. Due to that, it
required that modifier on multi-planar images to:

   1. Allow multiple planes.
   2. Perform YUV format lowering and extent adjustments.
   3. Use buffer_index to correctly map the given planes.

Fix these issues by removing or updating the code built on that
assumption.

anv: Use BO fences/semaphores for AcquireNextImage

Instead of doing a dummy submit on the command buffer for the fence or a
dummy semaphore and trusting in implicit sync, this commit moves us to
take advantage of implicit sync and just use the WSI image BO as the
fence.  Both semaphores and fences require a tiny bit of extra plumbing
to do this but the result is that we can get rid of a bunch of the extra
synchronization we're doing today.

anv: Use submit-time implicit sync instead of allocate-time

In 83b943cc2f24, we started making all VkDeviceMemory BOs resident all
the time.  One unfortunate side-effect of this is that every
vkQueueSubmit sets EXEC_OBJECT_WRITE on every WSI memory object which
means that X server or Wayland compositor, instead of waiting on the
last vkQueueSubmit to actually write the buffer, now waits on the last
vkQueueSubmit to from that driver instance relative to whenever the
compositor's GL driver instance calls execbuf.  This potentially leads
to a lot of extra synchronization that we didn't intend to have.

Instead, this commit makes it so that we leave WSI memory objects with
EXEC_OBJECT_ASYNC most of the time and only unset EXEC_OBJECT_ASYNC and
set EXEC_OBJECT_WRITE in the dummy execbuf that we do as part of
vkQueuePresent.  This should hopefully result in tighter integration
with the compositor, lower latency, and better performance.

Testing with DOOM 2016, this seems to reduce latency by at least a frame
if not two and makes the game much more responsive.  Testing was,
however, subjective, so we don't have any hard data on that.

anv: Always add in EXEC_OBJECT_WRITE when specified in extra_flags

Otherwise, we're trusting in the execbuf_add_bo which sets
EXEC_OBJECT_WRITE to to always be the first one that gets called.  This
is likely true for fences but it seems somewhat fragile.

vulkan/wsi: Provide the implicitly synchronized BO to vkQueueSubmit

This lets us treat the implicit synchronization that we need for X11 and
Wayland like a semaphore.  Instead of trusting the driver to somehow
figure out when that memory object needs to be signaled, we provide an
explicit point where the driver can set EXEC_OBJECT_WRITE and signal the
dma_fence on the BO.  Without this, we have to somehow track inside the
driver when WSI buffers are actually used to avoid extra synchronization
dependencies.
