move env helpers out of the config package (#24648)

go2rtc's create_config.py imported frigate.config.env, which ran the frigate.config package init and loaded every detector plugin. Since the onnxruntime 1.30 bump, importing onnxruntime takes about 5s on some hosts, so go2rtc started after Frigate's cameras and every ffmpeg process failed to connect to the restream until it came up. The env helpers now live in frigate.util.env, so go2rtc's config script no longer imports onnxruntime.
