Abtin Keshavarzian b212a0a748 [srp] implement AdvertisingProxy and define Dnssd platform APIs (#9268)
This commit adds a generic SRP Advertising Proxy implementation to
OpenThread core, which uses a set of newly defined `otPlatDnssd`
platform APIs for DNS-SD (mDNS) support on infrastructure network on
a Border Router.

`Srp::Server` provides `ServiceUpdateHandler` callback mechanism that
allows platforms to implement their own advertising proxy function.
While this is still supported, the new generic advertising proxy
implementation makes it easier to port and support the proxy function
on new platforms. The platform needs to provide the DNS-SD platform
APIs, which are designed to be simple and easy to implement.

The `AdvertisingProxy` directly interacts with `Srp::Server` and its
registered `Host` and `Service` entries, tracking whether an entry
has been successfully advertised, is currently being advertised, or
has been replaced by a new registration.

The `AdvertisingProxy` ensures that consecutive SRP updates for the
same host or service are committed on the server in the order they
are received, even if their advertisements are finished in a
different order. This is important for SRP Replication support, as
the server may receive a large number of SRP updates back-to-back for
the same host.

The `AdvertisingProxy` will also register key records for SRP host and
service instance names. This will keep the claim on the name of a
removed entry while its key lease is not expired. It is also used
when an SRP host registration has no off-mesh routable address.

This commit adds a detailed unit test `test_srp_adv_proxy` that
validates the `AdvertisingProxy` under many scenarios. The test
covers a range of cases, including delayed registration callbacks and
timeouts, new registrations replacing outstanding advertisements,
platform DNS-SD state changes and failures, host address changes
adding/removing OMR addresses.
