[SystemZ][z/OS] Distinguish between text and binary files on z/OS

This patch consists of the initial changes to help distinguish between text and binary content correctly on z/OS. I would like to get feedback from Windows users on setting OF_None for all ToolOutputFiles. This seems to have been done as an optimization to prevent CRLF translation on Windows in the past.
