Description
The FieldsAllocationStyle and CompactFields options were deprecated in JDJ 14 under JDK-8228753 and marked for obsoletion in JDK 15.

We need to:
- delete all code relating to the options
- update any test that may be specifying the options (e.g. VMDeprecatedOptions test)
- move the flags to the "obsoleted" section of the special flags table
- update any documentation that may refer to these flags

The changes to remove these options should be fixed before JDK-8228441 since that bug will retain some of the old code temporarily.

If this gets handled by JDK-8228441 that is fine, this can then be closed as a duplicate. I just wanted to make sure we didn't overlook the obsoletion if JDK-8228441 didn't get in to 15. Thanks.

[~fparain] do you want to remove these options are part of your field layout changes, or separately?
