Support MSC4222 state_after (#4487)

Browse Source 
* WIP support for state_after

* Fix sliding sync sdk / embedded tests

* Allow both state & state_after to be undefined

Since it must have allowed state to be undefined previously: the test
had it as such.

* Fix limited sync handling

* Need to use state_after being undefined

if state can be undefined anyway

* Make sliding sync sdk tests pass

* Remove deprecated interfaces & backwards-compat code

* Remove useless assignment

* Use updates unstable prefix

* Clarify docs

* Remove additional semi-backwards compatible overload

* Update unstable prefixes

* Iterate
