alts: Expose ChannelCredentials for the various negotiators

AltsChannelBuilder could be improved a bit more by removing the call to
InternalNettyChannelBuilder.setProtocolNegotiatorFactory. However, to do
that cleanest would require reworking how port is plumbed in
NettyChannelBuilder and potentially AbstractManagedChannelImplBuilder to
move getDefaultPort() to ProtocolNegotiator from ClientFactory. Saving
that for another day.
