tests/hlsl: Test clip/cull distance inputs.

tests/hlsl: Test clip distance semantic indexes above the 0-1 range.

vkd3d-shader/ir: Introduce vsir_opcode_is_fork_or_join_phase().

vkd3d-shader/ir: Introduce vsir_opcode_is_control_point_phase().

vkd3d-shader/ir: Assign new register indexes to clip plane signature elements.

vkd3d-shader/ir: Introduce vsir_signature_element_is_array().

vkd3d-shader/ir: Transform clip/cull inputs/outputs into arrays.

Takes care of transforming clip/cull system values from the Direct3D
convention of 2 4-component registers, into the SPIR-V/GLSL convention
of 8-element scalar float arrays.

This fixes SPIR-V validation errors in clip-cull-distance.shader_test,
as well as segfaults on Mesa 25.1.1-arch1.2 if those shaders are
executed regardless.

We create indexable temporaries of the appropriate size, and replace
accesses to clip/cull I/O signature elements with accesses to those
temporaries. The existing clip/cull signature elements are then replaced
with new scalar signature element arrays, and we copy the contents of
those I/O signature elements to/from the corresponding temporaries at
the start/end of the vsir program.

It is worth pointing out that the current implementation assumes that
every instance of the control point phase of a hull shader only writes
to the output registers of its control point, given by
vOutputControlPointID, and not to other control points. Shader
compilation will fail if that constraint is violated.

vkd3d-shader/ir: Move "has_descriptor_info" and "has_no_modifiers" to struct vsir_normalisation_flags.

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

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.

vkd3d-shader/spirv: Remove the unused "array_element_mask field" from struct vkd3d_shader_output_info.
