Re: [mediacapture-image] Provide a way to map POI to particular camera option (WB, AE, Focus)

@yellowdoge yes, UVC support 1 POI that can be configured to control WB, AE, focus or other parameters (separately or simultaneously).

Currently Image Capture API already supports multiple POIs, we can improve it and add fine grained feature control per POI.

This will be beneficial for most of the mobile devices (iOS, Android, Windows) as well as some desktop platforms (Windows, CrOS?). To keep backward compatibility, if parameter is not explicitly set for POI, we can assign POI to control all parameters.

For platforms that do not support multiple POIs, we can modify constrants, for example:

```
partial dictionary MediaTrackSupportedConstraints {
...
  // From boolean => unsigned short
  // boolean pointsOfInterest = true;
  unsigned short pointsOfInterest = 1;
...
}
```

What do you think?
