Refactor MAC address detection

[Gold856]

Description

MAC address detection didn't work on devices where PhotonVision doesn't manage the networking, as the logic pulled the interface name from the config. It also repeatedly spammed the logs with messages, which is super annoying and makes the logs harder to navigate. The system has been modified to use Java's NetworkInterface class to find a network interface on devices where PhotonVision doesn't manage networking, and the extra debug log has been removed since it doesn't tell us any information.

Resolves #1990.
