Revert "Check-in vulkan.h into third_party and use that instead of local sdk vulkan.h"

This reverts commit 3a3bc42b7d5b9d996debab1d2a05d2137c875bd7.

Reason for revert: still breaking android

Original change's description:
> 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.
>
