Just a heads up that I didn't check/verify the data that's being captured and sent to our server. That will need to be checked by @LorenzoMinto and team to make sure they're getting the correct data.

We'll also need to make sure that brave/brave-browser#17502 is fixed before we even thing of uplifting the above into Release:

• ensure that data is being removed from brave://local-storage and other locations if the user disables P3A
• ensure that data is being removed from server side when P3A has been disabled.
