Jonathan Hui dcbd870245 [dhcp6] obsolete DHCPv6 Server Unicast Option per RFC 9915 (#13146) ...

This commit updates the DHCPv6 Prefix Delegation (PD) client to
comply with RFC 9915, which obsoletes the Server Unicast option
(Option 12) and the UseMulticast status code.

Changes:
- Removed `mServerAddress` and `ProcessServerUnicastOption()` from
  `Dhcp6PdClient`.
- Modified `Dhcp6PdClient::SendMessage` to always transmit via
  multicast to `ff02::1:2`.
- Removed `UseMulticast` status code handling in `HandleReply()`.
- Added `otMessageFree` weak stub in simulation platform's
  `infra_if.c` to resolve linking errors on simulation radio-only
  targets when DHCPv6 PD client is enabled.
- Updated `test_dhcp6_pd_client.cpp` to expect multicast and
  removed the obsolete UseMulticast test case.
