vkd3d-shader/spirv: Do not handle division by zero for VSIR_OP_IDIV or VSIR_OP_IREM.

These correspond to the DXIL SDiv and SRem instructions, for which division by
zero is undefined. Division by zero is also undefined for DXIL UDiv and URem;
addressing those is slightly more involved.

tests: Replace the test_shader_instructions() "ps_udiv" test with a shader runner test.

vkd3d-shader/glsl: Handle integer operands in shader_glsl_movc().

We don't use these yet, but we're about to.

vkd3d-shader/ir: Handle integer division by zero in vsir_program_lower_udiv().

This achieves two things:
  - The GLSL backend no longer needs to handle this by itself. Likwise, the
    MSL backend won't have to either.
  - We no longer handle division by zero for DXIL UDiv and URem instructions,
    which leave this undefined.
