Allow a simple prop variable declaration to be treated the same as a rest declaration

[Thiagolino8]

Describe the problem

Currently, when declaring props as a simple declaration, the following error is returned: $props() can only be used with an object destructuring pattern

But if the destructuring pattern is used with the rest pattern, the generated code is a simple declaration

let props = $.rest_props($$props, []);

Describe the proposed solution

Treat this let props = $props() in the same way as this let {...props} = $props()

Alternatives considered

Not doing it, although receiving an object as a return instead of having to adopt the rest pattern is more intuitive

Importance

nice to have

Guiding developers to use named props with destructuring has sereral advantages:

• Self-documenting code: naming props explicity is a good idea:
  • Props are the public api of a component
  • Allows editors to show autocompletion for known props.
• Less bikeshedding discusions about using props.foo vs { foo }
