Greg Daniel c819e66993 Check-in vulkan.h into third_party and use that instead of local sdk vulkan.h
This change is needed since once we start getting support for varrying of extensions
and newer version support in general, we need a common vulkan header to compile off of.
Otherwise we will run into problems if clients have older headers that don't include
functions/symbols we are trying to use.

Additionally it has the benefit of not needing to add if SK_VULKAN around code in
include which wants to use vulkan symbols.

This is a reland of the reverted cl: https://skia-review.googlesource.com/13804
