[PATCH 2/7] anv: Add VK_EXT_display_surface_counter to anv driver [v2]

[Keith Packard]

This extension is required to support EXT_display_control as it offers
a way to query whether the vblank counter is supported.

v2:
	Add extension to list in alphabetical order

	Suggested-by:  Jason Ekstrand <jason at jlekstrand.net>
