idl_parser: Stop setting DATETIME property in IdlNode instances.

This makes the build non-deterministic, as even if the IDL contents do
not change the pickled files generated by collect_idl_files.py were
changing depending on the modification time of the files.

The DATETIME property seems to have been copied from the idl_parser.py
version that originated in //ppapi/generators (which still exists and
makes use of it) even though the bindings scripts do not use it for
anything.
