Terminal: Fix zoom when font size is missing

Browse Source 
If Terminal was configured with a typeface that does not have a font
for any given size, the zoom in and out button in the menu bar would
not work because font lookup was exact.

Use Font::AllowInexactMatch::Larger when zooming in and
Font::AllowInexactMatch::Smaller when zooming out to allow finding the
closest font size in the requested direction.
