[api-digester] Teach the api-digester about hasMissingDesignatedInitializers

Browse Source 
Because we won’t be serializing this attribute, add custom diagnostics for the cases where:

- We add @_hasMissingDesignatedInits to an open class, which means subclasses won’t be able to inherit its inits
- We remove @_inheritsConvenienceInitializers, which means APIs are removed
