At vkQueueSubmit time, for each batch with timeline semaphores to
signal, append cmd_buffers with feedback cmds to update the counter
value in its respective feedback slot.
Since multiple signals on the same semaphore could be pending at the
same time across batches/vkQueueSubmits, src slots and commands are
allocated on demand. These src slots can be reused after they've been
signaled (if the current semaphore counter is greater/equal than the
src value) and are cleaned up on vkDestroySemaphore.

Unlike fence feedback, commands to update timeline semaphore feedback
slots can't be fully pre-recorded because of the counter value input
for signaling timeline semaphores. To avoid fully recording commands
during vkQueueSubmit, pre-record commands that write a counter value
from a feedback "src" slot to the feedback "dst" slot. Then at
vkQueueSubmit, parse the signal semaphores and write the signal counter
value in the feedback src slot and append the command that writes from
that feedback src slot offset to the command buffer associated with the
signal semaphore.

Refactor into the following stages:
- prepare: Does an initial pass setting vn_queue_submission fields
and fixing up semaphores.
- alloc_storage: based on fields (including counts) from prepare,
calculate and allocate the amount of temporary storage needed.
- setup_batches: perform any modifications on the submission
batches using the allocated temporary storage.
- cleanup: free any temporary storage used.
Currently, only fence feedback needs alloc_storage and setup_batches
to append fence feedback to the submission but this slow will also
be utilized by upcoming timeline semaphore feedback.

When skiavk is the default system ui renderer, venus icd gets preloaded
into Zygote. However, Zygote access to render node is normally denied by
selinux except for legacy bootanimation purpose. This change fixes venus
icd loading to avoid invoking cros gralloc driver loading by moving the
perform op outside, so that we still get the memory footprint win.

Per Yiwei:
"For vn_QueueSubmit and other exposed Vulkan entry points, we keep the
original Vulkan variable namings. If within the same function you need
to use struct vn_queue *queue, then we prefix a _ to the args in the
exposed entry points, so it becomes VkQueue _queue.
For all other places:
VkObject obj_handle
struct vn_object *obj
The obj in this file can be queue, fence, sem, event, cmd, dev, etc."

Instead of calling an additional QueueSubmit for fence feedback, append
a SubmitInfo batch for fence feedback. This does require copying the

Right now, the WSI core supports copying WSI images to a linear buffer
for implementations that want the result in this form. This being said,
most of the blit logic can be re-used for image to image copies, and that's
exactly what we'll need if we want to hook-up DXGI swapchains in the
win32 WSI implementation. So let's rename a few fields so we no longer
imply that images are copied to a buffer, and the use_buffer_blit boolean
an enum so we can extend the implementation to support image -> image
copies.

This was found while debugging venus-lavapipe ci failure. It's a real
bug though no tests have caught this yet, but fixing this would regress
venus-lavapipe non-templated push tests if without the dependent lvp
fix. The sampler in the descriptor write can be garbled if the binding
has immutable samplers.

Without globalFencing, exportable fences and semaphores must instead
have their proxy vn_renderer_sync installed in the same renderer
ring_idx as ther last queue submissions to ensure they signal after
all work previously submitted to the same ring_idx. Exportable
fences/semaphores with a temporary (imported) payload don't need a proxy
vn_renderer_sync, since they already have a `poll()`able fd available.

With implicit fencing, the image has a fence that blocks scanout until
rendering is complete. virtgpu doesn't support implicit fencing yet, but
Sommelier (a VM Wayland compositor) does the wait by exposing the bo as
a GEM handle and waiting on all fences in userspace with a
DRM_IOCTL_VIRTGPU_WAIT before issuing the wl_surface commit.
During vkQueueSubmit involving wsi images, we follow with an empty
renderer submission on the corresonding ring_idx to install a fence
on the appropriate virtgpu fence context after the last rendering
submission.
