[PATCH vkd3d v2 1/3] tests: Test float4 UAV buffer load store.

July 11, 2022

This currently fails if the shader loads from the UAV, because it causes
vkd3d-shader to specify the R32ui format instead of Unknown.

Signed-off-by: Conor McCarthy <cmccarthy(a)codeweavers.com>

v2: Make the load/store test independent of the store test.
