[mediacapture-image] Consider converting attribute PhotoCapabilities into a getCapabilities() method

miguelao has just created a new issue for 
https://github.com/w3c/mediacapture-image:

== Consider converting attribute PhotoCapabilities into a 
getCapabilities() method ==
```ImageCapture``` has a [```readonly attribute PhotoCapabilities 
photoCapabilities;```](http://w3c.github.io/mediacapture-image/#image-capture-api),
 that is defined further on 
([here](http://w3c.github.io/mediacapture-image/#photocapabilities)) 
as:

> The photoCapabilities attribute of the ImageCapture object provides 
the photo-specific settings options and current settings values.

Retrieving and updating such a field is inherently racy with the rest 
of the Web Platform code, so I propose converting this ```attribute```
 into a ```Promise<PhotoCapabilities> getCapabilities(); [Throws]```, 
so basically the user/developer can control when/how often these 
numbers are retrieved, in an asynchronous way.
