ui: Decentralize track grouping and sorting

Plugins can now:
- Create TrackNodes and GroupNodes manually, giving them complete
  control over track grouping and sorting.
- Add their tracks and groups directly to the current workspace,
  eliminating the need for the registerTrackAndAutoShow() API.
- Control sorting relative to other tracks by specifying `sortOrder` on
  their TrackNodes and GroupNodes.
- Contribute tracks to common process and thread groups using:
  - getOrCreateGroupForProcess()
  - getOrCreateGroupForThread()

Plugins now take advantage of these new features to build the track
tree in a decentralized way, which (almost) removes the need for
TrackDecider. The scope of TrackDecider has been reduced to performing
the generic grouping of various global tracks based on track name.
