This commit updates how messages with an ALOC destination are forwarded. If the chosen ALOC destination is a child, its parent is used as the mesh destination unless the device itself is the parent. Additionally, if the selected ALOC destination is a sleepy child of the device, the parent node ensures to prepare the message for indirect transmission. These changes ensure correct forwarding to ED or SED devices when they register a service and want to receive messages on their service ALOC. This commit also adds a new test, `test-030-anycast-forwarding.py`, which validates the forwarding to ALOC addresses on both ED and SED devices.
