af736168f7 clients: Fix dmabuf feedback stall in simple-vulkan
When we receive dmabuf feedback, we hit the VK_SUBOPTIMAL path and
recreate the swapchain, returning early without submitting work.

However, we've already reset the fence before we do this, so we'll
block forever waiting for work that never comes to signal it.

Instead, we should reset the fence right before we know we're submitting
work.

Fixes: 75c37afa ("clients/simple-vulkan: New Vulkan client example")

a79e7c3e8d clients/simple-vulkan: move render_done semaphore to image
In some cases it is possible that a frame becomes available by its
fence but the last used swapchain image has still not been returned to
the swapchain. If the render_done semaphore is part of the frame struct
it will be reused and cause a validation error.
To prevent this from happening, move the render_done semaphore to the
image struct so that each of those semaphores is only used when the
associated image is safely acquired from the swapchain.

75c37afa62 clients/simple-vulkan: New Vulkan client example
Example to serve as a reference of a basic Wayland client using
Vulkan, contained in a single source file and with a minimal set
of dependencies.
Features incremental present (similar to swap_buffers_with_damage
from EGL) which is not commonly used by other Vulkan demos and is
useful to test the compositor.
Based on weston-simple-egl.
