sub: redecode cached packets on UPDATE_SUB_HARD or UPDATE_SUB_FILT

UPDATE_SUB_HARD causes all of the ass objects to reset in order to apply
the new style. UPDATE_SUB_FILT doesn't actually reset the sd, but it
should in order to update the actual filters so that was added here.
Doing this causes the current subtitle to be dropped. In the paused
cause, this concidentally works because command.c forces a video refresh
which then reloads the subtitle essentially. But while playing, the
subtitle will be dropped and you won't get anything until the next one
appears.

Instead of using video refreshes, what we can do is just always save the
last two subtitle packets in a cache and redecode them if needed. This
is much easier and also allows us to get rid of all the video refresh
logic in command.c. Fixes #12386.
