Allow filtering by "Date first seen"

[macobo]

Is your feature request related to a problem?

I want to:

1. analyze how new users are behaving vs old users
   a. By looking at pageviews/paths/funnel trends for these users
   b. By looking at session recordings from new users.
2. I want to see who my new users are so I'll know to reach out to them

Describe the solution you'd like

Add user property "Date first seen" to the user and allow filtering by it in trends/sessions/etc.

Also expose it under People page for querying.

Ideally this would not be a "string" field but a new, date field with its own autocompletion logic.

Describe alternatives you've considered

Adding the property manually in posthog-js or via a plugin

Additional context

Competitors:

Session recording tools (e.g. livesession) have a similar concept.

Could not find the feature in amplitude.

+1 for this. #2353 & related's design already introduced this property to the persons list. Being able to filter it would be a natural next step b

+1 would be great to have for the Funnels as well.

We want our Funnels to only analyze new users coming to the website without being influenced by returning visitors and users from previous periods.
