judyjoseph 4b30d09903 [macsec]: show macsec: add --profile option, include profile name in show command output (#13940)
This PR is to add the following

Add a new options "--profile" to the show macsec command, to show all profiles in device
Update the currentl show macsec command, to show profile in each interface o/p. This will tell which macsec profile the interface is attached to.
