Fixes include:
- Translating state keys that contain user IDs to their respective room
keys for both querying and sending state events
- **NOTE**: there may be design discussion needed on what should happen
when sender keys cannot be found for users
- A simple fix for kicking guests from rooms properly
- Logic for boundary history visibilities was slightly off (I'm
surprised this only manifested in pseudo ID room versions)

This PR adds a config key `room_server.default_config_key` to set the
default room version for the room server.

There are cases where a dendrite instance is unaware of a pseudo ID for
a user, the user is not a member of that room. To represent this case,
we currently use the 'zero' value, which is often not checked and so
causes errors later down the line. To make this case more explict, and
to be consistent with `QueryUserIDForSender`, this PR changes this to
use a pointer (and `nil` to mean no sender ID).

The previous version was getting **ALL** membership events (as
`ClientEvents`, so going through `NewEventFromTrustedJSONWithID`) for a
given room.
Now we are querying only locally joined users as `ClientEvents`, which
should **significantly** reduce allocations.
Take for example a large room with 2k membership events, but only 1
local user - avoiding 1999 `NewEventFromTrustedJSONWithID` calls just to
calculate the `roomSize` which we can also query by other means.
This is also getting called for every `OutputRoomEvent` in the userAPI.
Benchmark with 1 local user and 100 remote users.

When we're adding state to the database, we check which eventNIDs are
already in a block, if we already have that eventNID, we remove it from
the list. In its current form we would skip over eventNIDs in the case
we already found a match (we're decrementing `i` twice)
My theory is, that when we later get the state blocks, we are receiving
"too many" eventNIDs (well, yea, we stored too many), which may or may
not can result in state resets when comparing different state snapshots.
(e.g. when adding state we stored a eventNID by accident because we
skipped it, later we add more state and are not adding it because we
don't skip it)
This should fix two issues with backfilling:
1. right after creating and joining a room over federation, we are doing
a `/backfill` request, which would return redacted events, because the
`authEvents` are empty. Even though the spec states that, in the absence
of a history visibility event, it should be handled as `shared`.
2. `gomatrixserverlib: unsupported room version ''` - because, well, we
were never setting the `roomInfo` field..
