render: rename term->render.resizing -> term->interactive_resizing

But also, more importantly, logical fixes:

* Stash the number of new scrollback lines the stashed ‘normal’ grid
  should be resized *to*.

There’s also a couple of performance changes here:

* When doing a delayed reflow (tiocswinsz timer), call
  sixel_reflow_grid(term, &term->normal) - there’s no need to reflow
  sixels in the ‘alt’ screen.

* When doing a delayed reflow, free all scroll damage. It’s not
  needed, since we’re damaging the entire window anyway.

* Use minimum size for the temporary ‘normal’ grid (that contains the
  current viewport). We just need it to be large enough to fit the
  current viewport, and be a valid grid row count (power of 2). This
  just so happens to be the current ‘alt’ grid’s row count...
