AtlasEngine: Fix some Windows 10 <14393 bugs (#15485)

This fixes a couple spots where I wasn't properly checking
for the existence of some optional D2D interfaces.

## Validation Steps Performed
I haven't tested this and don't intend to do it just yet.
Windows Terminal requires build 19041 at least anyways.
