Add GoToSocial interaction controls vocabulary

Add type-safe vocabulary support for GoToSocial's interaction controls,
which allow post authors to specify who can like, reply to, or announce
their posts and to approve interactions.

New typeless embedded types (like Endpoints):

 -  InteractionPolicy: attached to posts via interactionPolicy, contains
    canLike, canReply, and canAnnounce sub-policies
 -  InteractionRule: each sub-policy with automaticApproval and
    manualApproval URI lists

New Activity subtypes for requesting interaction approval:

 -  LikeRequest, ReplyRequest, AnnounceRequest

New Object subtypes for proving approved interactions:

 -  LikeAuthorization, ReplyAuthorization, AnnounceAuthorization
    (with interactingObject and interactionTarget properties)

New properties on Object:

 -  interactionPolicy, approvedBy, likeAuthorization,
    replyAuthorization, announceAuthorization

All Object subtypes now include the GoToSocial namespace context
(https://gotosocial.org/ns) in their defaultContext so that inherited
GTS properties serialize correctly in compact JSON-LD.
