Seungha Yang 426535f3a6 d3d11screencapture: Add WinRT API based capture mode
Add Windows Graphics Capture (WGC) API based screen capture mode.
The conditions where this mode is used:
* Explicitly requested by user (capture-api property)
* To capture specific window
* When DXGI desktop duplication API does not work on hybrid graphics systems
  (e.g., multi-gpu laptop)

Full features of this implementation require Windows 11. And Windows 11
SDK is required to build this feature.
