  -----------
  [MLIR][LLVM] Add distinct identifier to the DISubprogram attribute (#77093)

This commit adds an optional distinct attribute parameter to the
DISubprogramAttr. This enables modeling of distinct subprograms, as
required for LLVM IR. This change is required to avoid accidential
uniquing of subprograms on functions that would lead to invalid LLVM IR
post export.
