[Mesa-dev] [PATCH 02/23] vulkan: Add #ifdef hack to vk_android_native_buffer.h

[Chad Versace]

This patch consolidates many potential `#ifdef ANDROID` messes
throughout src/vulkan and src/intel/vulkan into a simple, localized
hack. The hack is an `#ifdef ANDROID` in vk_android_native_buffer.h
that, on non-Android platorms, avoids including the Android platform
headers and typedefs any Android-specific types to void*.

This hack doesn't remove *all* the `#ifdef ANDROID`s in upcoming
patches, but it does remove a lot.

I first tried implementing VK_ANDROID_native_buffer without this hack,
but eventually gave up when the yak shaving became too much.
