[CUI] Add SQL model and custom track for CUI page loads.

* Introduce two new data models
  - chrome_page_loads - stores fcp/lcp stats
  - chrome_critical_user_actions - stores all CUIs in a
    single table.
* Adds new diff tests for the new data model (fcl/lcp only)
  This will expand as more CUI metrics are added.
* Add a new CUI track with details panel to the UI, hidden
  behind a flag. This track summarizes the navigation duration
  based on fcp and lcp timings only.
