Vulkan: only report refresh duration (add new call for new way)

As part of discussions within Khronos, it was decided that
VK_GOOGLE_display_timing should only report one refresh duration for a display,
and assume that it's refresh rate is fixed (which is the case for our current
devices).

This commit adds the new macro/function that will be used long-term.  A future
commit will remove the old macro/function, once it is no longer used (since the
plumbing crosses repository boundaires.

Test: Manually tested with a modified cube demo, that reports the refresh
duration returned from this extension.
