de-MSC-ifying space summaries (MSC2946) (#3134)

Browse source 
- This PR moves and refactors the
[code](https://github.com/matrix-org/dendrite/blob/main/setup/mscs/msc2946/msc2946.go)
for
[MSC2946](https://github.com/matrix-org/matrix-spec-proposals/pull/2946)
('Space Summaries') to integrate it into the rest of the codebase.
- Means space summaries are no longer hidden behind an MSC flag
- Solves #3096

## Does Dendrite support Space Summaries?
Yes, [Space Summaries](https://github.com/matrix-org/matrix-spec-proposals/pull/2946) were merged into the Matrix Spec as of 2022-01-17 however, they are still treated as an MSC (Matrix Specification Change) in Dendrite. In order to enable Space Summaries in Dendrite, you must add the MSC to the MSC configuration section in the configuration YAML. If the MSC is not enabled, a user will typically see a perpetual loading icon on the summary page. See below for a demonstration of how to add to the Dendrite configuration:
Yes
## Does Dendrite support Threads?
Yes, to enable them [msc2836](https://github.com/matrix-org/matrix-spec-proposals/pull/2836) would need to be added to mscs configuration in order to support Threading. Other MSCs are not currently supported.
```
mscs:
mscs:
- msc2946
- msc2836
```
Similarly, [msc2836](https://github.com/matrix-org/matrix-spec-proposals/pull/2836) would need to be added to mscs configuration in order to support Threading. Other MSCs are not currently supported.
Please note that MSCs should be considered experimental and can result in significant usability issues when enabled. If you'd like more details on how MSCs are ratified or the current status of MSCs, please see the [Matrix specification documentation](https://spec.matrix.org/proposals/) on the subject.
