Improve logic for overriding Proxy from all NetworkInterfaces

[NghiaTranUIT]

🐶 Brief

Our current implementation is unable to get the correct name of iPhone device when sharing internet via USB. Consequently, Proxyman couldn't override it properly.

We should come up better solution to get correct name, then passing to networksetup cli.

👑 Criteria

• Remove old implementation
• Use SystemConfiguration framework to get NetworkInterface name
• Only return Enable one
• Override Proxy config in background

All done 💯

🤯 Changelogs

• New solution to get all NetworkDevices Name from SystemConfiguration framework
• Run on background thread to boost the launch time
