ime: track IME focus independently from keyboard focus

Replace the seat->ime.focused boolean with a terminal instace pointer,
seat->ime_focus.

Set and reset this on ime::enter() and ime::leave() events, and use
this instead of seat->kbd_focus on all other IME events.

This fixes two issues:

a) buggy compositors that sometimes sends an IME enter event without
  first having sent a keyboard enter event.

b) seats may be IME capable while still lacking the keyboard
  capability. Such seats will *always* see IME enter events without a
  corresponding keyboard enter event.
