Add full support for RFC 9460's SvcParams list.
Amend the existing `dns_svcb_rr` record by a vector of new
`dns_svcb_param` records containing aptly typed SvcParamKey and
SvcParamValue pairs. Example output:
```
@load base/protocols/dns
event dns_HTTPS( c: connection , msg: dns_msg , ans: dns_answer , https: dns_svcb_rr ) {
for (_, param in https$svc_params)
print to_json(param); # filter uninitialised values
}
```
```
