Make helper invocations take part in subgroupQuad operations #1798

  1. Make helper invocations take part in subgroupQuad*

    Subgroup quad operations should be marked as WQM because
    helper invocations take part in subgroup operations if enabled.
    
    This addresses a potential issue with Vulkan CTS test:
    dEQP-VK.draw.renderpass.shader_invocation.helper_invocation
    
    Rework use of WQM intrinsics in subgroup operations to be
    based only on shader stage and not use knowledge of operations
    used in SPIRV.
