Allow use of Path Replacement options in Path fields in Trends (and other non-Paths insights)

Feature request

Is your feature request related to a problem?

I would like to have a better breakdown based on paths. Posthog already supports path cleaning in the Paths Insight...ideally that would be extended whenever a Path field is referenced in an Insight.

Describe the solution you'd like

Add ability to apply 'Path Cleaning Rules' here.

i.e. support for pathReplacement=True in

"breakdownFilter": {
      "breakdown_type": "event",
      "breakdown": "$pathname",
      "breakdown_normalize_url": true
    }

Describe alternatives you've considered

Creating path based Actions for every path I want to track and manually adding each Action as a Series. Very cumbersome.
