Support Actors/Statuses with multiple types

[ekiru]

This would address #7193:

It allows processing type properties with multiple values where one of the values is a recognized/supported type in several places by:

• replacing checks that an ActivityStreams Object's type equals a specific value with calls to the preexisting equals_or_includes? helper from JsonLdHelper and
• replacing checks that an Object's type is among a set of values with calls to a new equals_or_includes_any? helper method.

I've added a spec testing that the ResolveAccountService handles Actors whose type property is ["as:Person", "vcard:individual"] as if they were just a Person. I can add more specs testing other places if that seems necessary.
