Add mechanism for detecting if a user is tabbed out of Resonite

Is your feature request related to a problem? Please describe.

Due to issue #3238 Users have been using this bug to detect if they are tabbed out If this issue is fixed then users who relied off of its functionality will be left dry in the water that's why I'm requesting a more robust implementation of detecting if a user is tabbed out of Resonite

Describe the solution you'd like

Component or node to detect that the user is tabbed out

Describe alternatives you've considered

Using the bug found in #3238 This is used to detect if the cursor is at 0, 0, 0, Which means you're tabbed out if the issue is fixed the cursor won't be at that position so it's not a very good long term solution

This would be a good desktop equivalent to the "Is Platform Dash Open" node for a lot of systems and avatar functions.

As Frooxius highlighted here #3238 (comment):

We generally advise using quirks and bugs like this as reliable method for detecting various things - if you do that, we do not make any guarantees that it'll keep working.

We can consider adding a proper mechanism in this case, depending on the complexity, but we will not hold up bugfixes because of this in general - if you don't want it to break, don't use stuff like that.

I think this addition could be considered at the least at some point then.
