Damage only terminal inside `alacritty_terminal`

The damage tracking was including selection and vi_cursor which were
rendering viewport related, however all the damage tracking inside
the `alacritty_terminal` was _terminal viewport_ related, meaning that
it should be affected by `display_offset`.

Refactor the damage tracking so `alacritty_terminal` is only tracking
actual terminal updates and properly applying display offset to them,
while `alacritty` pulls this damage into its own UI damage state.

Fixes #7111.
