Feature Request

Ability to set fetchPriority attribute on script tags.

Webpack doesn't offer any way to set fetchPriority attribute on script tags that are managed/added by webpack.

I propose adding output.scriptFetchPriorty option with values boolean = false, string: 'high' | 'low' | 'auto'
When !== false, it is used in LoadScriptRuntimeModule to add the attribute to the script tag.
