Apple II - refactor states to use Serializer (#1859) 

* apple II - poc to redo binary states to use the Serializer and pass it into virtu

* virtu - savestate logic for Video

* AppleII - serialize more components with AppleSerializer

* cleanup

* refactor MachineEvents to store delegates to call and have the calling code interact with an enum, prep work for serializing this class

* apple II - first attempt at serializing Machine events

* cleanup

* add isvblank to savestates

* put more things in savestates, cleanup

* cleanup

* cleanup, save more things

* cleanup, fixes

* cleanup, save more things

* virtu - savestate fixes

* cleanup

* save CurrentDisk in savestates
