Check for depthBounds support in shader builtin frag depth tests

Depth bounds testing was enabled without checking for feature support
in a couple of tests. With this change, tests that don't need this
feature leave it disabled, whereas other tests (currently only
dEQP-VK.glsl.builtin_var.fragdepth.*) now throw NotSupported when
the device doesn't support it.

Affects:

dEQP-VK.clipping.*
dEQP-VK.glsl.builtin_var.*

Components: Vulkan

VK-GL-CTS issue: 685

Change-Id: I44d94142e295ff135ad1a55d0d6e212b65994257
