TextureVk: Transition to the first usage if needed 

In Vulkan images are created in no particular layout and must be
transitioned before they can be used. This didn't appear before because
the test were creating the textures with not initial usage and then
transitioned them. This isn't the case with InputStateTest, which is
what uncovered this issue.
