vulkan: Add EXT_direct_mode_display [v2]

Add support for the EXT_direct_mode_display extension. This just
provides the vkReleaseDisplayEXT function.

v2:
	Adopt Jason Ekstrand's coding conventions

	Declare variables at first use, eliminate extra whitespace
	between types and names. Wrap lines to 80 columns.
