Hide any commandline (cooked read) we have before we begin a resize, and
show it again after the resize.

PR Checklist

Detailed Description of the Pull Request / Additional comments

Basically, during a resize, we try to restore the viewport position
correctly, and part of that checks where the current commandline ends.
However, when we do that, the commandline's current state still
reflects the old buffer size, so resizing to be smaller can cause us
to throw an exception, when we find that the commandline doesn't fit in
the new viewport cleanly.

By hiding it, then redrawing it, we avoid this problem entirely. We
don't need to perform the check on the old commandline contents (since
they'll be empty), and we'll redraw it just fine for the new buffer size

Validation Steps Performed

  • ran tests
  • checked resizing, snapping in conhost with a cooked read
  • checked resizing, snapping in the Terminal with a cooked read
