Additional functions: EnumDisplayDevices

[weitzhandler]

Added implementation for the EnumDisplayDevices.

I wasn't sure how whether you update the shipped/unshipped files manually or with a tool, so I'm waiting for input on that.

Once this gets merged, EnumDisplaySettings and ChangeDisplaySettings will be next.

@AArnott
I see the error is about the API reference. Is this added manually or by tool? I couldn't figure out the proper way.

@weitzhandler There's a Roslyn Analyzer which can update the API reference. Here's how I got it to work:

1. Open the project with Visual Studio

2. Open the file which contains the new API

3. In the upper left corner of the file editor in Visual Studio, select {ProjectName} (net20). (It's left of the dropdown which contains the list of classes/members in your file)
   

4. Go to the line which contains the new API

5. Click the tooltip or SHIFT + F10
   

6. Select Add {Method} to public API / Fix all occurrences in: Project

It's my experience that this functionality is a bit finicky; sometimes I have to try multiple times before the API is actually updated.

Thanks for contributing. There are a few repo-conforming changes to make, and I'll be happy to merge.
