Implement a type IsNever, which takes input type T.
If the type of resolves to never, return true, otherwise false.

For example:

type A = IsNever<never> // expected to be true type B = IsNever<undefined> // expected to be false type C = IsNever<null> // expected to be false type D = IsNever<[]> // expected to be false type E = IsNever<number> // expected to be false
