Chore: update Microsoft.Windows.CsWin32 and modernize code

[DeagleGross]

Because package was not updated, there are some native types value references which are using hardcoded values like here:

aspnetcore/src/Servers/HttpSys/src/NativeInterop/HttpApi.cs

Line 88 in 6061280

SupportsClientHello = IsFeatureSupported((HTTP_FEATURE_ID)11 /* HTTP_FEATURE_ID.HttpFeatureCacheTlsClientHello */) && HttpGetRequestPropertySupported;

We should update the package and the code.
