Disallow contextual "any"

[use-strict]

Problem is described here: microsoft/TypeScript#4126

It was suggested that TSLint might be able to handle the given case with a special rule. I see that something like this was already suggested back in 2014 (#80). Have things changed since then or is it still a no-go?

I haven't investigated type-based rules much yet but this sounds useful and should be doable.

[use-strict]

@adidahiya , it seems I can't implement this without #680. Blocked tag? :(

Is this still an issue now that we have no-unsafe-any?
