ui: Simplify & merge 'simple' tracks & debug tracks

- Merge debug* tracks and simple* tracks.
- Add createQuerySliceTrack() & createQueryCounterTrack, which are
  async track factories that create a perfetto table from a query and
  return a track that uses that prefetto table.
  - The reason we do this up front rather than lazily in the track's
    onCreate function is because the details panel needs the source
    table, which could be selected before the track has been 'created'.
    This is what debug tracks have always done, so it's not really
    much of a change.
- Rename simple_*_track.ts to query_*_track and move to public/lib.
- Sensible defaults for track columns, as 90% of callsites were
  pointlessly specifying these repeatedly:
  - Slice tracks: {ts: 'ts', dur: 'dur', name: 'name'}
  - Counter tracks: {ts: 'ts', value: 'value'}
- Make argColumns optional, as 90% of callsites passed an empty list
  here.
- Changed addDebug*Track() to reuse createQuery*Track() on the
  backend.
- Tweaked interface of addDebug*Track() to use the same defaults as
  createQuery*Track(), and move all args into an object so all args are
  named - for improved readability.
- Remove 'Debug' theming from the slice table details panel as it's
  used for 'query' slice tracks as well, which are not debug tracks.
