rutabaga_gfx: add stream_renderer_vulkan_info

Browse source 
The exact internals of the API may change though.  For example,
using a device UUID is a less error-prone than using physical
device index.

However, this is sufficient to get gfxstream external memory on
atleast some platforms.

BUG=b:235485545
TEST=compile and run ./deqp-vk with kFeature_ExternalBlob enabled
