[Piglit] v2: ext_memory_object: Test sampling memory exported from Vulkan

[Topi Pohjolainen]

First draft only contained the Vulkan rendering part. This revision
adds the remaining bits: importing the memory to GL, creating a texture
for it and sampling it.

While there is now a fair bit of infrastructure that can be re-used, I
feel that a lot more work remains.

Along the way I needed GL support and drafted some initial support for
Intel Mesa driver:

git://people.freedesktop.org/~tpohjola/mesa:ext_memory_object

Jason: I was wondering how GL drivers are meant to deduce the tiling.
       I suppose this is meant to happen outside the GL-api but I
       couldn't think of anything else than trying to read that from
       the buffer object (see the Intel driver hook).
