[child] update how IPv6 addresses of a child are managed (#2485)

This commit updates/enhances the `Child` class methods related to
managing of the list of IPv6 addresses associated with a child. The
new model provides APIs to add or remove an IPv6 address, check if the
list contains an address, and a method to iterate through all IPv6
addresses of a child. The `mle_router` and `address_resolver` and NCP
implementations are updated to use the new APIs.

This commit also adds a unit test `test_child` to verify  the newly
added methods.
