Fix URL parsing with double-width characters

Since double-width characters are followed by an empty cell containing
only the `WIDE_CELL_SPACER` flag, the URL parser would stop once
encountering the cell after a double-width character.

By skipping cells that contain the `WIDE_CELL_SPACER` flag and
incrementing the URL length by unicode width of the character instead of
cell count, this can be resolved for both URL launching and URL
highlighting.

Fixes #2158.
