App: Seperate pipeline pause and close

[niley7464]

This patch seperates pipeline pause and close.
Also, now we can see pipeline status in main activity.

This PR needs nnstreamer/nnstreamer#4488

What do the error messages above mean? Is pause->close OK, but stop isn't?

I left the explanation too abstractly.

I called ml_pipeline_start-> ml_pipeline_stop (pause) -> ml_pipeline_start

Then, restared server recived data like below.

2024-06-13 12:45:57.783 22590-22666 nnstreamer-edge         ai....eamer.ml.inference.offloading  D  Received command:0 (num:0)
2024-06-13 12:45:57.784 22590-22666 nnstreamer-edge         ai....eamer.ml.inference.offloading  E  Failed to get host info.
2024-06-13 12:45:57.784 22590-22666 nnstreamer-edge         ai....eamer.ml.inference.offloading  D  Send error cmd to close connection.

Data should have command enum and memory number like this.

2024-06-13 12:48:29.742 22884-22977 nnstreamer-edge         ai....eamer.ml.inference.offloading  D  Received command:2 (num:1)
2024-06-13 12:48:29.758 22884-22982 nnstreamer-edge         ai....eamer.ml.inference.offloading  D  Received command:1 (num:1)

So I thought the error message appeared when ml_pipeline_close called in PR description might be the cause.

+) The problem was not exactly related to the close function, caps were not set when restarting.
