RFR: 8374658: Consider use of "included" rather than "enclosed" in jx.a.p.Processor [v3]

[Joe Darcy]

> The use of "enclosed" in javax.annotation.processing.Processor looks to be using a more colloquial definition than the JLS-eque notion of "enclosed" used in parts of the javax.lang.model API.
> 
> Instead, this PR proposes to switch from "enclosed" to "included," a term already used in RoundEnvironment for the concept in question.
