perfetto-ui: Parametrize track with data type
At the moment each Track must cast its track data to the correct type.
This CL moves this to the abstract base class by parametrizing Track with
a 'Data' type (as we do with Config).
In addition to avoiding the same boiler plate in each Track this means
TrackController no longer needs a direct dependency on globals.ts.
Also rename MyTrackConfig to Config and MyTrackData to Data as these names
should never leave the my_track directory anyway.
