WebAssembly.Table methods are incorrect

[ten3roberts]

Describe the Bug

The WebAssembly table can hold either externref or anyfunc. However, the API in js-sys uses Function in its methods, rather than the more permissive JsValue.

Additionally, functions accepting a second parameter are not reflected, such as the constructor, and the grow method which can take a second (optional) init parameter.

The API should ideally reflect the JavaScript API and allow for these use cases

grow() (and others with missing optional parameters) could be amended by just adding new methods.

For get() and set(), we either do a breaking change, considering these are already broken to some degree, or just introduce new methods that take and return new types.
Right now at least I don't see why we would break those, adding new methods sounds good to me, we could even deprecate the old ones.

Happy to review a PR!
