Implement stable support for MSC3882 to allow an existing device/session to generate a login token for use on a new device/session (#15388)
Implements stable support for MSC3882; this involves updating Synapse's support to
match the MSC / the spec says.

Continue to support the unstable version to allow clients to transition.
