[Feature Request] [SPIR-V] no vk::ext_decorateon function parameters

[Erfan-Ahmadi]

Is your feature request related to a problem? Please describe.

In the example below (full godbolt link), only the x variable gets correctly decorated with Aliased.
The OpFunctionParameters %a and %b remain undecorated.

// A simple function with an input and a return value
void SimpleAdd([[vk::ext_decorate(/*spv::DecorationAliased*/20)]] inout float a, [[vk::ext_decorate(/*spv::DecorationAliased*/20)]]  inout float b) {
    a = 1.0f;
    b = 2.0f;
}

[numthreads(64, 1, 1)]
void main(uint3 DTid : SV_DispatchThreadID, 
          uint3 Gid  : SV_GroupID,           
          uint  GTid : SV_GroupIndex)        
{
    [[vk::ext_decorate(/*spv::DecorationAliased*/20)]]  float x = 43;
    SimpleAdd(x, x);
    OutputBuffer[GTid] = x;
}

Describe the solution you'd like
I'd like to be able to decorate function parameters

Additional context
make sure to compile with -fcgl or -O0 to avoid inlining the function
