[Splash screen] Show per user, not per user per space

[alexfrancoeur]

The splash screen looks fantastic! I know we had an async conversation in the last PR and I thought we had concluded to go with per user vs. per user, per space (#21353 (comment)). Though reading through the comments, I'm not really sure if we did.

Today, we are showing the splash screen per user per space. This can be a bit frustrating as both a new and power user. Would it be possible to only show the splash screen per user if there is no data instead of per user, per space?

Ideally, we fix this before 6.5

@alexfrancoeur just to confirm, are you seeing the screen appear in other spaces after clicking "Explore on my own"? In my earlier testing, dismissing the screen in one space would be respected in all spaces.

If you choose to add data in one space, then I think the dialog continues to appear in subsequent spaces. Is this the scenario you'd like changed? If so, it might have to be something simple, like always hiding the welcome screen after pressing either button, even if they choose not to add sample data after saying they want to.

The welcome screen will check to see if any index patterns exist before displaying. This check uses the Saved Objects Client, which is transparently space-aware, and will only return results for the current space. In other words, we don't have a way to search across all spaces here.
