To specify a DRM device node for the VK_KHR_display backend,
WSI_DISPLAY_DRI_DEV environment variable needs to be set. If
WSI_DISPLAY_DRI_DEV is not set, the VK_KHR_display backend
now scans all DRM device node, and uses the first node
that has a display connected.

Introduce util::mutex, util::recursive_mutex
and util::unique_lock; switch WSI layer call sites to it.
All locks are acquired via try_lock(), no system_error leaks.

Adds a swapchain create info extension for creating an image using
external memory. This removes the need for modifying the
image_create_info in the display and wayland backends. There is still
code duplication left in these backends though, because swapchain
allocation needs to know the selected format. This will be removed when
the swapchain images will be created from the swapchain image creator.
Moves the definition of drm_format_pair to drm_utils.
Removes two step initialization from swapchain_wsi_allocator.
