[ads] Clear ads history, conversion URLs, etc when browsing history is cleared

[diracdeltas]

Description

If the user goes to brave://settings/clearBrowserData to clear "browsing history" for a given time range, stored ad data associated with that time range should also be cleared since it often includes partial browsing history. Similarly this should happen on exit every time if they have "clear browsing data on exit" set.

Data to be deleted:

• [x] Default/ads_service/database.sqlite:
• [x] Default/ads_service/client.json:
• [x] Default/ads_service/confirmations.json:
• [x] Default/Preferences/brave/brave_ads:

Per discussion with @btlechowski - removed feature/rewards as this is ads focused, as such he will cover this testing 👍🏻
