Since #3334 didn't change much on d.m.org, this is another attempt to
speed up startup.
Given moderation bots like Mjolnir/Draupnir are in many rooms with quite
often the same or similar ACLs, caching the compiled regexes _should_
reduce the startup time.
Using a pointer to the `*regexp.Regex` ensures we only store _one_
instance of a regex in memory, instead of potentially storing it hundred
of times. This should reduce memory consumption on servers with many
rooms with ACLs drastically. (5.1MB vs 1.7MB with this change on my
server with 8 ACL'd rooms [3 using the same ACLs])
[skip ci]
This should fix#3004 by making sure we also update our in-memory ACLs
after joining a new room.
Also makes use of more caching in `GetStateEvent`
Bonus: Adds some tests, as I was about to use `GetBulkStateContent`, but
turns out that `GetStateEvent` is basically doing the same, just that it
only gets the `eventTypeNID`/`eventStateKeyNID` once and not for every
call.

This has numerous upsides:
- Less type casting to `*Event` is required.
- Making Dendrite work with `PDU` interfaces means we can swap out Event
impls more easily.
- Tests which represent weird event shapes are easier to write.
Part of a series of refactors on GMSL.
Replaced with types.HeaderedEvent _for now_. In reality we want to move
them all to gmsl.Event and only use HeaderedEvent when we _need_ to
bundle the version/event ID with the event (seriailsation boundaries,
and even then only when we don't have the room version).

* Move currentstateserver API to roomserver
Stub out DB functions for now, nothing uses the roomserver version yet.
* Allow it to startup
* Implement some current-state-server storage interface functions
* Add missing package
