Quentin Gliech a6d1122b1f Add a usernameAvailable GraphQL query for anonymous lookups ...

Exposes a new query telling whether a given username is available for
registration, and if not, why: already taken, or rejected by the
registration policy. A username reserved on the homeserver side is
deliberately reported as taken, mirroring the ambiguity of the
registration form, which doesn't tell the two apart either.

Because the query reveals whether a username exists, it is rate-limited
per requester, configurable through the new
`rate_limiting.username_availability` option.
