Add PowerPoint compatible screen size for Impress

I realized that Impress does not have the same screen
size as PowerPoint. tdf#142286, tdf#142288

When I load a PowerPoint slide into Impress,
it was a custom size, but when I add this screen size,
it shows up with the screen size name.

And when I load a slide with the added screen size
into PowerPoint, it also shows up with the PowerPoint
preset screen size name and not the custom size.

The screen sizes I have added are as follows

* Widescreen (Current PowerPoint default)
* On-scren Show (4:3)
* On-scren Show (16:9) (Google slide defualt)
* On-scren Show (16:10)
