[9.x] Inherit crossorigin attributes while preloading

[timacdonald]

"CORS"...the thing every developer wants to wake up and hear about 💆‍♂️

This PR improves upon the preloading functionality with Vite by having preload tags inherit the crossorigin attribute from their standard script / link tag counterpart.

If an app is adding a crossorigin attribute...

Vite::useScriptTagAttributes([
    'crossorigin' => true,
]);

That results in the following HTML...

<link rel="modulepreload" href="https://exmaple.com/build/assets/app.0b16cbf2.js">
<script type="module" src="https://exmaple.com/build/assets/app.0b16cbf2.js" crossorigin></script>

The trouble is that the two tags must have matching crossorigin tags, otherwise a double fetch is performed. To manually solve this, you can specify the crossorigin tag for preload tags...

Vite::useScriptTagAttributes([
    'crossorigin' => true,
]);

Vite::usePreloadTagAttributes([
    'crossorigin' => true,
]);

After this PR, there is no need to manually specify the preload tag attribute for crossorigin, as it will be inherited from the useScriptTagAttributes setup.

This means that the following setup...

Vite::useScriptTagAttributes([
    'crossorigin' => true,
]);

results in the following HTML...

<link rel="modulepreload" href="https://exmaple.com/build/assets/app.0b16cbf2.js" crossorigin>
<script type="module" src="https://exmaple.com/build/assets/app.0b16cbf2.js" crossorigin></script>

where both tags have the same crossorigin attribute. A develop may still override the preload tag attribute for the crossorigin attribute, however I can't see any reason why you would ever want to do this.
