This change removes the win2d (Direct2D wrapper) dependency by using D2D directly. This removes the manual step of adding the win2d to any new react-native-windows projects that want to use react-native-svg. It is also a stepping stone to an easier Fabric implementation for windows.
Starting in v13, the switch to Fabric changed the color prop values sent to the native side, so all colors on Windows were defaulting to black. Updated the property setters to handle that change and also added support for the SVG color prop / "currentColor".
Addresses build issues seen in #1803, #1809, and #1863 by making updating RNSVG.vcxproj and making it more resilient to template/version changes in react-native-windows.
