SPIR-V Built-In
ShaderIndexAMDX
Index assigned to the shader within the workgraph

Decorating a variable with the ShaderIndexAMDX built-in decoration will
make that variable contain the index of the shader specified when it was
compiled, either via
VkPipelineShaderStageNodeCreateInfoAMDX::index or by the
ShaderIndexAMDX execution mode.
