Björn Linse 5020daa6e5 ui/terminal: make terminal state redraw like any other state
Previously, ordinary redraws were missing from terminal mode. Instead,
there was an async callback that invoked update_screen() on terminal
data regardless of mode (as if :redraw! was invoked by a timer).

This created some issues:

- async changes to an unrelated ordinary buffer were not always redrawn in
  terminal mode
- screen cursor position was not properly updated in terminal mode (partial
  fix, will be properly fixed in a follow up PR)
- ad-hoc logic was needed for interaction with special states such as
  inccommand or horizontal wildmenu.

Instead redraw terminal mode just like any other state. This disables forced
redraws in cmdline mode, which were inconisent which async changes to
normal buffers (which are not redrawn in cmdline mode).
