migrate otelgrpc from deprecated interceptors to stats handler API (#998)

- Replace otelgrpc.StreamServerInterceptor() and otelgrpc.UnaryServerInterceptor() with otelgrpc.NewServerHandler()
- Upgrade go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc from v0.58.0 to v0.63.0
- Stats handler approach is the recommended way forward and more efficient than interceptor-based approach
