Vulkan: Implement color mask and depth mask bits

These two features are heavily used in the
functional.depth_stencil_clear.* dEQP tests.

Enable a bunch of color/depth/stencil clear tests, however there is
still 2 tests in particular that are giving me trouble. I will work
on them separately in a subsequent change.
