The behavior of the existing ElementScannerN classes is to *not* visit type parameters as part of the actions of their visitType and visitExecutable methods.

This is a consequence of type parameters not being considered part of the enclosed elements of a type or executable.

This behavior of skipping type parameters may be unexpected by users and has led to code like an internal RoundElement method "ElementScanningIncludingTypeParameters" (JDK-8032230).

The behavior should at least be noted for the current visitors and should likely be changed when the ElementScanner(N+k) is eventually added.
