Subject: [PATCH] gfxstream: move generate-gfxstream-vulkan.sh script

This moves the generate-gfxstream-vulkan.sh script
to upstream Mesa too.  Right now, Mesa is the source
of truth for both guest and host codegen.

There needs to be a simple way to invoke genvk.py
for users.  The script assumes the AOSP directory
structure to find gfxstream host, but the user may
also pass the path to gfxstream as the first argument.

Please run this from the src/gfxstream/codegen directory.
