Allow selecting "prejoin" events by state keys (#14642)

Browse source 
* Declare new config

* Parse new config

* Read new config

* Don't use trial/our TestCase where it's not needed

Before:

```
$ time trial tests/events/test_utils.py > /dev/null

real	0m2.277s
user	0m2.186s
sys	0m0.083s
```

After:
```
$ time trial tests/events/test_utils.py > /dev/null

real	0m0.566s
user	0m0.508s
sys	0m0.056s
```

* Helper to upsert to event fields

without exceeding size limits.

* Use helper when adding invite/knock state

Now that we allow admins to include events in prejoin room state with
arbitrary state keys, be a good Matrix citizen and ensure they don't
accidentally create an oversized event.

* Changelog

* Move StateFilter tests

should have done this in #14668

* Add extra methods to StateFilter

* Use StateFilter

* Ensure test file enforces typed defs; alphabetise

* Workaround surprising get_current_state_ids

* Whoops, fix mypy

### `room_prejoin_state`
Controls for the state that is shared with users who receive an invite
to a room. By default, the following state event types are shared with users who
receive invites to the room:
- m.room.join_rules
- m.room.canonical_alias
- m.room.avatar
- m.room.encryption
- m.room.name
- m.room.create
- m.room.topic
This setting controls the state that is shared with users upon receiving an
invite to a room, or in reply to a knock on a room. By default, the following
state events are shared with users:
- `m.room.join_rules`
- `m.room.canonical_alias`
- `m.room.avatar`
- `m.room.encryption`
- `m.room.name`
- `m.room.create`
- `m.room.topic`
To change the default behavior, use the following sub-options:
* `disable_default_event_types`: set to true to disable the above defaults. If this
is enabled, only the event types listed in `additional_event_types` are shared.
Defaults to false.
* `additional_event_types`: Additional state event types to share with users when they are invited
to a room. By default, this list is empty (so only the default event types are shared).
* `disable_default_event_types`: boolean. Set to `true` to disable the above
defaults. If this is enabled, only the event types listed in
`additional_event_types` are shared. Defaults to `false`.
* `additional_event_types`: A list of additional state events to include in the
events to be shared. By default, this list is empty (so only the default event
types are shared).
Each entry in this list should be either a single string or a list of two
strings.
* A standalone string `t` represents all events with type `t` (i.e.
with no restrictions on state keys).
* A pair of strings `[t, s]` represents a single event with type `t` and
state key `s`. The same type can appear in two entries with different state
keys: in this situation, both state keys are included in prejoin state.
Example configuration:
```yaml
room_prejoin_state:
disable_default_event_types: true
disable_default_event_types: false
additional_event_types:
- org.example.custom.event.type
- m.room.join_rules
# Share all events of type `org.example.custom.event.typeA`
- org.example.custom.event.typeA
# Share only events of type `org.example.custom.event.typeB` whose
# state_key is "foo"
- ["org.example.custom.event.typeB", "foo"]
# Share only events of type `org.example.custom.event.typeC` whose
# state_key is "bar" or "baz"
- ["org.example.custom.event.typeC", "bar"]
- ["org.example.custom.event.typeC", "baz"]
```
*Changed in Synapse 1.74:* admins can filter the events in prejoin state based
on their state key.
