Fix cursor expansion across wide chars

This fixes a regression introduced in 0.7.0 where the block cursor would
not expand across both cells anymore when on top of a wide char spacer
cell.

The logic to always move the cursor on the wide char instead of the
spacer has been moved to the alacritty_terminal crate, making sure it is
always performed before any processing in the UI.
