Simplify SA.GetValidOrderAuthorizations2 so that it no longer conditions the query on the status, expiry, or registration ID of the authorization rows. This gives the query much better performance, because it no longer tries to use an overly-large index, and fall back to large row-scans when the query planner decides the index is too large.
While we're here, also improve the return type of GetValidOrderAuthorizations2, so that instead of returning a map of names to authorizations, it simply returns a list of authzs. This both reduces the size of the gRPC message (once the old map is fully removed), and improves its correctness because we cannot count on names to be unique across multiple identifier types.
Finally, improve the RA code which calls SA.GetValidOrderAuthorizations2 to handle this improved return type, to make fewer assumptions about identifier types, and to separate static authorization-checking from CAA rechecking.
