8236225: Remove expired flags in JDK 17
8256717: Expire the long term obsoleted VM flags

The newly expired flags in 17 are removed from the flag table, as are all of the long term obsolete flags that had no explicit expiration release.

Updated any remaining references to the obsolete flags that are now expired.

Updated the man page to move flags from obsolete section to expired (removed) section. Note the manpage also shows changes to the illegal-access flag, this is a change that was made to the closed manpage source for JDK 16 but has not yet been pushed into the open java.1 version. This part of the change can be ignored.

Testing: tiers 1-3 and local testing of modified tests. I'm also checking for any JCK tests that may still use the legacy obsolete flags.

Thanks,
David
