<rdar://problem/11449953> Change Debugger::SetOutputFileHandle() so that it does not automatically initialize the script interpreter in order to transfer its output file handle to it

This should delay initialization of Python until strictly necessary and speed-up debugger startup
Also, convert formatters for SEL and BOOL ObjC data-types from Python to C++, in order to reap more performance benefits from the above changes
