[Piglit] ext_memory_object: Support for vulkan rendering

[Topi Pohjolainen]

In order to test memory sharing between Vulkan and GL one needs
to be able to write with one and read with the other. This series
introduces Vulkan rendering support taken from crucible.

There is work-in-progress test utilizing this. It setups the
pipeline and renders using GLSL shaders copied from

crucible/src/tests/func/shader/fragcoord.c

The test itself is only half way there. There is, however, quite
a bit in the Vulkan render support which I thought worth sharing.
