Poor error message elaborations for array-like types

[DanielRosenwasser]

let point = [3, 4] as const;

function distanceFromOrigin([x, y]: [number, number]) {
    return Math.sqrt(x ** 2 + y ** 2);
}

distanceFromOrigin(point);

Argument of type 'readonly [3, 4]' is not assignable to parameter of type '[number, number]'.
  Type 'readonly [3, 4]' is missing the following properties from type '[number, number]': pop, push, reverse, shift, and 6 more.

This is bad to show to beginners. Here's a few things we could be doing better.

1. If a source type is a ReadonlyArray (for all E), and a target type is an Array, then give a specialized error message that ReadonlyArrays can't be assigned to Arrays.

   A 'ReadonlyArray' cannot be assigned to an 'Array' because 'Array's can be mutated.
   

2. If the source type is a readonly tuple, and the target is a plain tuple or array-like type...

   A 'readonly' tuple cannot be assigned to a mutable array-like type.
   

3. If one side is a tuple type, and the other isn't array-like, just don't elaborate at all. Nobody cares about missing push, pop, and 6 other members...
