RFR: 8355792: Remove expired flags in JDK 26

[David Holmes]

Please review these trivial start-of-release updates in relation to expired flags:

- the expired flag table is updated to remove entries for expired flags (2 this time)
-  the Java man page "Removed options" section is updated (none are being removed (expired) in JDK 26)

Thanks
