tests/hlsl: Test clip/cull distance semantics as arrays.

Browse Source 
Arrays are allowed for clip/cull distance semantics. Their maximum size
is 2 since that's the maximum amount of registers allowed for clip/cull
distances.

Indirect addressing of these arrays is allowed on shader model 6.

These tests are introduced after the transformation of clip/cull
input/outputs into arrays in vsir since otherwise they segfault.
