PRovide a way to actually enable the natvis diagnostics in VS Code

[nikitalita]

There doesnt seem to be any way to enable the diagnostic output if you're using this with VS Code; I have no idea how to debug natvis issues without this ability.

You should be able to enable natvis diagnostic in your launch.json.

E.g.

{
   "program": ...,
   "natvisDiagnostics": "verbose"
}

See https://github.com/microsoft/vscode-cpptools/blob/8d42c49b77aadb5ae4286f21efcd159601118805/Extension/package.json#L3730

Ah, it needs to be in the logging object, like this:

{
   "program": ...,
   "logging": {
         "natvisDiagnostics": "verbose",
    },
}

@WardenGnaw could you write, please, in what window logs should appear?
