[routing-manager] PdPrefixManager to clear prefix bits when extending length (#9249)

Browse Source 
This commit updates the `RoutingManager::PdPrefixManager::Process()`
method to `Tidy()` the prefix before setting the prefix length and
potentially extending the prefix to `kOmrPrefixLength` (64 bits).
This ensures that extended bits in the prefix are set to zero.
