[Triple] Add XXX filter automatically when XXX is enabled

[ev1lQuark]

Problem description

In the process of configuring and starting otel.tracing, set it according to the following configuration:

        ins, err := dubbo.NewInstance(
		dubbo.WithName("dubbo_sample_tracing"),
		dubbo.WithProtocol(
			protocol.WithTriple(),
			protocol.WithPort(20000),
		),
		dubbo.WithRegistry(
			registry.WithZookeeper(),
			registry.WithAddress("127.0.0.1:2181"),
		),
		dubbo.WithTracing(
			trace.WithEnabled(),
			trace.WithStdoutExporter(),
			trace.WithW3cPropagator(),
			trace.WithRatioMode(),
			trace.WithRatio(0.5),
		),
	)

But the otel tracing filter is not append to service.filter slice. So as the trace.WithEnabled() is correctly set by user, the otel.Tracing module is not working as expected.

Todo

During the startup process, if a module is enabled, the corresponding filter will be automatically added, allowing users to configure module enable logic easily.
