Xi Ge f7406e6c3c swift-api-digester: diagnose changing of the necessity of new witness table entry as ABI breakage ...

Protocol requirements may not necessarily add new entries to the witness table if
it's inherited from super protocol. This patch teaches the json dump to
include a flag indicating whether a protocol requirement requires new
witness table entry and diagnoses the change of such flag as ABI
breakages.
