Expand coverage for these tests by using combinatorial test
parameterization. Covers more cases and expands coverage to
compressed textures. This caught a bug on Vulkan where only the
first region for multi-layer compressed texture copies was cleared.
It also caught a driver bug on some Intel platforms, where clearing
the non-zero mip of a depth texture does not work.
