[routing-manager] process RDNSS options and track addresses (#11328)
This commit introduces a mechanism in `RoutingManager` to parse and process Recursive DNS Server (RDNSS) options within received Router Advertisement (RA) messages. The list of discovered RDNSS addresses is tracked (per router) by `RoutingManager`, applying the advertised lifetime to properly age the discovered entries. This commit adds a new public API to retrieve the list of tracked RDNSS addresses, along with a callback mechanism where OpenThread users can register to be notified of changes to the RDNSS list. This callback is invoked when any of the following changes occur: - A new RDNSS address is advertised by a router. - A previously discovered address is removed due to the router advertising it with a zero lifetime. - A previously discovered address has aged out (its lifetime expired without being re-advertised). - `RoutingManager` determines that the router advertising the address is now unreachable, resulting in the removal of all its associated entries. This commit also adds corresponding CLI commands for the new API. Furthermore, `test_routing_manager` is updated to include a test case covering all the newly added behaviors in detail.
