X11: Implement text input focus

Browse source 
Map explicit text input focus to XIM input context focus with XSetICFocus
and XUnsetICFocus.

On focus out, reset preedit through the existing X11 helper before
unsetting IC focus, preserving its conservative behavior.  Native FocusIn
only restores XIC focus when text input focus has not been explicitly
disabled.
