gfxstream: use standard Vulkan headers and new auto-gen flow

This modifies gfxstream to use standard Vulkan headers,
and updates to 1.3.269.

Previously, the headers were mostly standard, but added in
vk_android_native_buffer into vulkan_core.h.  That breaks down
when using auto-gen scripts from outside gfxstream, which will
happen in a subsequent patchset.

For vk_native_buffer_android, we can simply provide a
vk_android_native_buffer_gfxstream.h.

Long-term, vk_native_buffer_android.h should be deprecated in
favor of VK_ANDROID_external_memory_android_hardware_buffer, in
Android's libvulkan and elsewhere.

For the Vulkan headers, the new procedure is generate them in the
directions found here in the following repos:

https://github.com/KhronosGroup/Vulkan-Headers
https://github.com/KhronosGroup/Vulkan-Hpp

Those headers can be copied over using cp.  For gfxstream encoder
+ decoders, that's still generated via ./generate-gfxstream-vulkan.sh

The only catch is you must use the same vk.xml for Vulkan-Headers,
Vulkan-Hpp, and for the cereal generator.  The recommended flow
is use whatever the xml is in Vulkan-Headers ToT and copy to
Vulkan-Hpp and cerealgenerator.py before running those scripts.

The End2End tests that relied on vk_android_native_buffer were
also modified.  Long-term, the AHB extension could be used
instead of ANB for tests.
