This implements `SetForceFullRepaintRendering` and adds a new `SetGraphicsAPI` function. The former toggles `Present1` on and off and the latter allows users to explicitly request Direct2D/3D. On top of these changes I did a minor cleanup of the interface, because now that DxRenderer is gone we don't need all that anymore. Closes #14254 Closes #16747 ## Validation Steps Performed * Toggling Direct2D on/off changes colored ligature support ✅ * Toggling Present1 on/off can be observed in a debugger ✅ * Toggling WARP on/off changes GPU metrics ✅ --------- Co-authored-by: Dustin L. Howett <duhowett@microsoft.com>
