Add a debug binding and mode to highlight (green tint) what has
been rendered through vulkan-renderer composition. This is useful
to visually identify/debug clients which have been offloaded to
DRM planes, since those won't go through the renderer composition
process and therefore won't be highlighted the same way.
Since this is the first debug mode in vulkan-renderer, add some
initial infrastructure to handle debug bindings.

The VkSpecializationMapEntry use was incorrect here, it requires the
struct offset to be in the second entry.

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.
