refactor(redraw): no type argument in update_screen()

This was used in the past with assumption that curwin/curbuf
is "special" but this has not been true since basically forever
at this point.

Reduce NOT_VALID/CLEAR panic in options.lua . These should not
be set if an effect of the option is causing something
which by itself invokes redraw_later().
