Rewrite annotation invalidation strategy

First, move style mutation code out of StyleParser and into AnnotationManager,
coalescing it with the mutation code for shape layers.

Second, allow AnnotationManager to keep track of stale tiles entirely
internally. There's no reason to pass sets of TileIDs around.

Third, correct the logic for invalidating the shape source. Since
AnnotationManager does not track shape invalidations on a tile-by-tile basis,
don't try to invalidate the shape source tile-by-tile.
