Remove explicit SDK version for Windows builds

[chrisglein]

Fix SDK build error if 10.0.16299.0 is not installed:

 i Build configuration: Debug
 i Build platform: x64
 × Build failed with message 4:10>C:\Users\redactedUser\.nuget\packages\microsoft.ui.xaml\2.8.0\build\Common.targets(10,5): error : Microsoft.UI.Xaml nuget package requires TargetPlatformMinVersion >= 10.0.17763.0 (current project is 16299) [D:\GitHub\redacted\node_modules\react-native-video\windows\ReactNativeVideoCPP\ReactNativeVideoCPP.vcxproj]. Check your build configuration.

See react-native-async-storage/async-storage#810 for a similar fix.
And these

• Remove explicit SDK version for Windows builds react-native-picker/picker#483
• Remove explicit SDK version for Windows builds react-native-clipboard/clipboard#177
• fix(Windows): Fix issue when emptying nav stack on Windows software-mansion/react-native-screens#1890

Previously, after bringing down package dependencies you'd have to retarget the SDK version for the module project.

This change was tested by applying a patch-package of the vcxproj to an RNW app and doing a clean build. Basically, if it builds, it's good. No runtime effect.

This is ok for me, thank you for these pull requests. Just a question, does it imply some necessary change on the application side to configure the sdk ? I think no, but I am asking as I am in doubt !

Nope, no change needed on the application side. If the app has an SDK version specified (which it absolutely will have) then this module will match that SDK version with this change. Previously it would fight with the app's specified SDK and you'd need to have both SDK versions installed in order to build. Which could have been transparent if you happened to have multiple SDKs installed, or would be a nuisance to prompt you to go install an SDK version you didn't really need (and also be a drain on your disk space 😉).
