[MLIR][LLVM] Add distinct identifier to DICompileUnit attribute (#77070)
This commit adds a distinct attribute parameter to the DICompileUnit to enable the modeling of distinctness. LLVM requires DICompileUnits to be distinct and there are cases where one gets two equivalent compilation units but LLVM still requires differentiates them. We observed such cases for combinations of LTO and inline functions. This patch also changes the DIScopeForLLVMFuncOp pass to a module pass, to ensure that only one distinct DICompileUnit is created, instead of one for each function.
