Support fetching the spaces summary via GET over federation. (#9947)

Per changes in MSC2946, the C-S and S-S APIs for spaces summary
should use GET requests.

Until this is stable, the POST endpoints still exist.

This does not switch federation requests to use the GET version yet
since it is newly added and already deployed servers might not support
it. When switching to the stable endpoint we should switch to GET
requests.
