Decouple render_fence_fd from the DRM output, in particular so that
it is allowed in headless outputs (for upcoming dmabuf renderbuffers).
Also simplify the code to make it clear that it is handled per-output.

For swapchain outputs, 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.

The captured buffer cannot be just memcpy'ed to the destination as
it might overwrite existing pixels outside of the capture region.
For now switch it to a pixman composition.

A Vulkan renderer for weston, based on the GL renderer.
The goal is to impose the least requirements as possible on Vulkan
implementations, as to allow even Vulkan 1.0 (or early development)
drivers to run a Wayland compositor. Any additional features or
extensions are made optional if possible.
Currently supports drm, wayland, x11 and headless backends.
As of this implementation, this is still considered an experimental
renderer.
