* Convert tabbedview to functional component
The 'Tab' is still a class, so now it's a functional component that
has a supporting class, which is maybe a bit... jarring, but I think
is actually perfectly logical.
* put comment back
* Fix bad tab ID behaviour
* Make TabbedView a controlled component
This does mean the logic of keeping what tab is active is now in each
container component, but for a functional component, this is a single
line. It makes TabbedView simpler and the container components always
know exactly what tab is being displayed rather than having to effectively
keep the state separately themselves if they wanted it.
Based on https://github.com/matrix-org/matrix-react-sdk/pull/12478
