fix: Improve 2-way audio detection (#2293)

- For Frigate cameras, you must be running at least [integration
v5.12.0](https://github.com/blakeblackshear/frigate-hass-integration/releases/tag/v5.12.0).
 - Closes: #2191 

Includes a significant refactor of cameras, and the introduction of a
`2-way-audio` capability that is dynamically fetched from `go2rtc`. One
gotcha is if you previously had a substream with 2-way audio, you may
need to modify

```yaml
 - camera_entity: camera.foo
    capabilities:
      disable_except:
        - substream
```

... to ...

```yaml
 - camera_entity: camera.foo
    capabilities:
      disable_except:
        - substream
        - 2-way-audio
```
