"requiredExtensions" extension API

[LordCat0]

This adds the ability for extensions to have the "requiredExtensions" attribute in the extensions info in which the VM will attempt to load the extensions if not already added. Below is a mock-up extension I used in which everything seems to work as expected.

(async Scratch => {
    class Extension {
        getInfo(){return {
            id: "testing",
            name: "Testing EXT",
            blocks: [],
            requiredExtensions: [
                "pen",
                "motion",
                "https://sharkpools-extensions.vercel.app/extension-code/Turbo-Skins.js",
                "https://extensions.turbowarp.org/fetch.js",
                "https://extensions.turbowarp.org/runtime-options.js"
            ]
        }}
    }
    Scratch.extensions.register(new Extension);
})(Scratch);
