fix(dontet): iso-8601 date strings get turned into DateTime (#2058)
When a ISO-8601-encoded date is passed from JavaScript to the .NET app, the JSON deserializer would interpret that as a `DateTime` instead of passing the string un-touched. This is a problem, since the jsii kernel protocol has a dedicated wrapper key for DateTime values (`$jsii$date`). This PR adds a compliance test around this particular scenario, and disabled `DateTime` handling from the standard deserializer (the wrapped values are still processed correctly). > This PR also changes the way the .NET test package generates the > tested libraries (`jsii-calc` & dependencies) so that instead of > generating NuGet packages, it only generates C# projects. This makes > the experience of debugging the tests **much** nicer, and reduces the > likelihood of cached build artifacts getting in the way. Fixes aws/aws-cdk#10513
