vkd3d-shader/spirv: Decorate non-array descriptor variables as well.

Browse Source 
Commits 343c7942e1 and
94c74d2c00 moved applying the NonReadable
and Coherent decorations from spirv_compiler_emit_resource_declaration()
to spirv_compiler_build_descriptor_variable(), but unfortunately missed
the non-array path in the latter function.

The missing NonReadable decoration causes segmentation faults in
rasteriser-ordered-views.shader_test (among others) on my Intel SKL GT2
setup in particular.
