[ncp] implement ncp version of otPlatDnssdRegisterHost (#10893)

Browse Source 
This commit implements ncp version of otPlatDnssdRegisterHost.
1. move the position of `SPINEL_PROP_DNSSD_STATE` in `spinel.h`
   because it was by mistake put within the range of
   `SPINEL_PROP_SRP_SERVER`. The value is unchanged.
2. A template method `DnssdUpdate` is added because the same process
   works also for DNSSD service and key record which will be added in
   following PRs.
