Most Vulkan drivers are happy to compile a pipeline with interstage
interface mismatches, even if the pipeline will be broken. Metal,
and therefore MoltenVK, instead doesn't and errors out immediately.
This allows the Vulkan runner to execute in environments which do
not support geometry shaders, most notably MoltenVK. In particular,
that enables SM<4 shaders to run in such environments
The used UAV formats are explicitly added in the [require] section of
every test that uses them.
Some of these tests were failing on Intel UHD graphics 770 because of
missing support for additional UAV load types, explicitly requiring
these formats allows these tests to be skipped.
The first thing that's broken is that the "sType" field isn't
VK_STRUCTURE_TYPE_PIPELINE_SHADER_STAGE_CREATE_INFO, but we're also
passing invalid "module" handles.
