hterm: change CSI-J-3 to clear scrollback

We've long had CSI-J-3 (clear scrollback) wired to behave like CSI-J-2
(clear screen) because letting the remote clear local scrollback might
not be the best behavior.  Add a config setting to control it so we can
change the CSI-J-3 extension to match xterm where we got it from.
