RFR: JDK-8321073: Defer policy of disabling annotation processing by default

[Joe Darcy]

To allow more time for build tools to accommodate changes in javac's default annotation processing policy, disabling annotation processing by default will be deferred one release to JDK 23. 

This PR re-enables implicit annotation processing by default _for JDK 22_. It is an anti-delta of  JDK-8306819.

Please also review the CSR to restore the previous behavior for JDK 22:
