Subject: [PATCH] fix(Metal): force a full rebuild in `setFontGrid`

This was causing garbled text due to a non-rebuilt rows referencing an
outdated atlas when the DPI changed but not the grid dimensions, which
could be caused by a variety of things such as the quick terminal
slide-in, dpi scaling changes on sleep/wake, moving windows between
displays because of closing/opening the laptop lid, etc.
