[react-native] Support for react-dom@19

[kerwanp]

Description

In react-dom@19 the function findDOMNode has been removed. Instead the ref actually contains the Element.
To support both 18 and 19 version we check wether findDOMNode is defined.

On as side note, I gave react-compiler a try on our Expo app and it failed. It seems related to Builder as the type prop of the JSX element provided for components with children become undefined with react-compiler.

In the following example children[0].type is a JSX.Element with $$typeof: Symbol(react.memo). With react-compiler it becomes undefined.

{
    name: "MyComponent",
    component: ({ children }) => {
       console.log(children[0].type)
       return children
    },
    canHaveChildren: true,
}

I will find some time for testing and maybe opening an other PR for react-compiler support
