new: usr: Add support for EDNS ZONEVERSION option

`dig` and `named` can now make requests with an EDNS `ZONEVERSION` option present.

Two new `named.conf` options have been added: `request-zoneversion` and
`provide-zoneversion`.  `request-zoneversion` is `off` by default. `provide-zoneversion`
is `on` by default.

Closes #4767

Merge branch '4767-implement-zoneversion' into 'main'
