-Add a new define to wrap the output semantic that we want to be post declare as precise. -Modify DXC-SIRV to add the NoContraction decorator on precise output semantics. -Modify spirv_glsl to post declare as precise output semantics -Example: out precise float4 gl_positon; will add precise gl_position; post declaration.
