[master][chassis][show-runningconfig] Fix the show runningconfiguration all issue on the Supervisor

[mlok-nokia]

What I did

bgp is not supported on Supervisor card, "show runningconfiguration all" fails on the Supervisor since the bgp services is disable. Add code to check if bgp state in the FEATURE table is able before it tries to get the BGP configuration to avoid the error. Fix issue sonic-net/sonic-buildimage#18276

How I did it

Since BGP feature state is disabled in the FEATURE table on Supervisor card, add method is_bgp_feature_state_enabled() to the bgp_util.py check the BGP feature state. Modify the "show runningconfiguration all" to call the is_bgp_feature_state_enabled(), then call the run_ngp_show _command to get the bgp configuration.

How to verify it

1. Execute the "show runningconfiguration all" command on Supervisor. The following output should be shown without any error.
