Numerous MLIR functions return instances of `StringRef` to refer to a non-owning fragment of a string (usually owned by the context). This is a relatively simple class that is defined in LLVM. Provide a simple wrapper in the MLIR C API that contains the pointer and length of the string fragment and use it for Standard attribute functions that return StringRef instead of the previous, callback-based mechanism.
