Do not accept pattern_type from user input in push rules. (#15088)
Internally the push rules module uses a `pattern_type` property for `event_match` conditions (and `related_event_match`) to mark the condition as matching the current user's Matrix ID or localpart. This is leaky to the Client-Server API where a user can successfully set a condition which provides `pattern_type` instead of `pattern` (note that there's no benefit to doing this -- the user can just use their own Matrix ID or localpart instead). When serializing back to the client the `pattern_type` property is converted into a proper `pattern`. The following changes are made to avoid this: * Separate the `KnownCondition::EventMatch` enum value into `EventMatch` and `EventMatchType`, each with their own expected properties. (Note that a similar change is made for `RelatedEventMatch`.) * Make it such that the `pattern_type` variants serialize to the same condition kind, but cannot be deserialized (since they're only provided by base rules). * As a final tweak, convert `user_id` vs. `user_localpart` values into an enum.
