fix(options): disallow empty 'fdc' and 'scl' (#16765)
Empty string values for these options aren't actually allowed, but
check_opt_strings allows empty string options.

It so happens that 'scl' handles empty string like "auto", but empty 'fdc'
causes glitchiness (win_fdccol_count returns an incorrect value).

Just disallow empty string values for these options completely.
