Follow-up to https://github.com/matrix-org/matrix-public-archive/pull/36
Render pipeline separation of concerns:
1. Run in `child_process`
2. Hydrogen render
It's now just a generic `child_process` runner that runs the Hydrogen render in it. This eliminates the windy path of the 1-4 steps that was only held together by the file names themselves.
We added the description in https://github.com/matrix-org/matrix-public-archive/pull/54 but then made a fix to one of the after render errors, https://github.com/matrix-org/matrix-public-archive/pull/57, which exposed that the description is then overriden when the powerlevel changes.
We now just override the getters directly instead of the internal fields which are overwritten internally.

This also fixes a warning from Hydrogen in the console:
```
disposable not found, did it leak? {kind: 'disabled', description: Array(3)}
```
Fix missing `room.observePowerLevels()` throwing error after render.
```
Uncaught (in promise) TypeError: this._room.observePowerLevels is not a function

```
Doesn't affect main-line rendering but the error is annoying to see. More Hydrogen boilerplate 😞
Use `DisabledComposerView` instead of no composer to add message:
> You're viewing an archive of events from 2022-02-08. Use a [Matrix client](https://matrix.to/#/!HBehERstyQBxyJDLfR:my.synapse.server) to start chatting in this room.
Also refactors some of the `views` and `viewmodels` out to their own files
We now run the Hydrogen render in a `child_process` so we can exit the whole render process. We still use the `vm` to setup the browser-like globals. With a `vm`, everything continues to run even after it returns and there isn't a way to clean up, stop, kill, terminate the vm script or context so we need this extra `child_process` now to clean up. I don't like the complexity necessary for this though. I wish the `vm` API allowed for this use case. The only way to stop a `vm` is the `timeout` and we want to stop as soon as we return.
Fix https://github.com/matrix-org/matrix-public-archive/issues/34
Remove `matrix-bot-sdk` usage in tests because it didn't have timestamp massaging `?ts` and it's not really necessary to rely on since we can just call the API directly 🤷. `matrix-bot-sdk` is also very annoying having to build rust crypto packages.
We're now using direct `fetch` requests against the Matrix API and lightweight `client` object.
All 3 current tests pass ✅
Get this project running again after a few months of changes
from `hydrogen-view-sdk` and now finally after
https://github.com/vector-im/hydrogen-web/pull/693
merged to make the SDK friendly to locally link and develop on.
