dump: Unify detection of fullwidth characters

Browse Source 
In DUMP_FUNCTION_SPECIALIZED (used by elinks --dump), detect the
second cell of double-cell (aka fullwidth) characters by comparing to
UCS_NO_CHAR, like add_document_to_string does.  Don't use
unicode_to_cell for this any more.

Also, ignore the colors and attributes of the second cell; don't
output any escape sequences for them.
