[mle] simplify signaling of DUA address change (#10296)

Browse Source 
This commit simplifies how `ProcessAddressRegistrationTlv()` signals
DUA address changes. Signaling now occurs after all child addresses
are registered, using a new `SignalDuaAddressEvent()` method. This
method checks the old and new DUA addresses to determine the
appropriate event to signal.

Additionally, `Child::GetDomainUnicastAddress()` is updated to return
an `Error` and copy the DUA address into a provided `Ip6::Address`
reference.
