sys/queue: Update to version from FreeBSD 14.1

This adds various new macros (_SAFE variants in particular) for
queue operations.

Consequence is removal of CIRCLEQs which were removed in FreeBSD
(and later in other BSDs) in 2000 (sic!), original commit citation:
"CIRCLEQs are a disgrace to everything Knuth taught us in Volume 1
Chapter 2. Retire them before anybody starts to use them again.
Use TAILQ instead, it provides the same functionality."
