feat: adds leave and kick support

[ricardogarim]

wip – built on top of feat/federation-reactions, should be merged right after that one.

As per FDR-60, FDR-62, and FDR-85, this pr covers the following use cases:

1. User leaves a channel from Rocket.Chat
2. User leaves a room from another matrix node and we process it via homeserver

The following use cases won’t be fully tested right now and will be revisited soon, once power level changes are merged - since they rely on permission updates and will be a good opportunity to better understand how those features behave:

1. User gets kicked from another matrix node and we process it via homeserver
2. User with admin rights removes another user from Rocket.Chat

Must be tested along with RocketChat/Rocket.Chat#36572.
