- nb-javac is pulled from regular class path instead of modifying the
   boot class path during build
 - Copying SetupLimitModulesProbe from nbbuild/antsrc to
   apisupport.ant at build time.
 - CI: test apisupport.ant on JDK 17.

 - modules which set requires.nb.javac could not bump the language
   level, so they used the module requirement as workaround
 - others might have simply forgotten to bump the property

remove most OpenIDE-Module-Java-Dependencies entries from manifest

 - the build sets it automatically, all entries which have
   the same value as javac.release can be removed
 - exceptions: gradle, nbjshell9 and extexecution.processs.jdk9
   which were left out for now
