Subject: [PATCH] fix(ivy): allow `FunctionExpression` to indicate a method
 declaration (#25406)

In some code formats (e.g. ES5) methods can actually be function
expressions. For example:

```js
function MyClass() {}
// this static method is declared as a function expression
MyClass.staticMethod = function() { ... };
```

PR Close #25406
