The [official C# extension] is maintained by Microsoft and enables
IDE-like support for C# in VS Code.
If a user opens this repository in VS Code, they will be prompted to
install it if they haven't already installed it. After installation, the
extension will also prompt the user to install the .NET SDK if it's not
found.

This doesn't actually remove the targets just yet (that will require a bit more work), but rather remove the target options from our IDE configurations to reduce accidental usage of net471/mono.
Adds debug/release launching. Cleans up much. Also updates tasks.json schema to 2.0.0 which supports multiple commands.
Can't use until https://github.com/Microsoft/vscode/issues/22250 is fixed.
