[circular_raw_ostream] Delegate is_displayed to contained stream

raw_ostream has an is_displayed() member function that determines if the stream
is connected to a console for display or is connected to a file/pipe. By
default, is_displayed() returns false, and derived classes like raw_fd_ostream
override it. Because circular_raw_ostream wraps another stream, its result for
is_displayed() should be the same as that stream.
