[feat] Match JS popup box behavior with browser (alert, prompt and confirm should be sync)

[hugoattal]

Describe the problem

I discovered that alert(), prompt() and confirm() returns a promise in Tauri.
I'd love JS to make these functions a promise, but as of right now, they are sync and blocking.

The problem is that a lot of libraries rely on it for stuff like this

if (confirm("Are you sure?")) {
    console.log("You done it!")
}

In the browser:
It will wait for the user input and block the process
If the user click on Yes, it will log You done it!
If the user click on No, it won't log anything

In Tauri:
The user will be asked Are you sure?
And at the same time, it will always log You done it! (since a promise is truthful)

Describe the solution you'd like

I think the default behavior should be the same as the browser.
Another solution would be a flag or a plugin that allow those functions to be sync.
