RFR: JDK-8309870: Using -proc:full should be considered requesting explicit annotation processing [v2]

[Joe Darcy]

> Address a small omission to the recent addition of "javac -proc:full", regard "-proc:full" as explicitly requesting annotation processing. Also add "-A" to the list of options indicating explicit annotation processing was requested.
> 
> The intention is to backport this bug fix to JDK 21 too.
