[core] Merge LiveTileData into VectorTileData

Browse Source 
To encapsulate the differences, this introduces an abstract
GeometryTileMonitor class, with concrete VectorTileMonitor and
AnnotationTileMonitor implementations, and makes pbf parsing for
VectorTile data happen lazily in getLayer, since we want that to
happen on the worker thread, rather than when VectorTile is created.

Fixes #2792
