feat(geo): Increase default BingTile zoom shift from 6 to 7 (#15759)

Summary:
Pull Request resolved: #15759

The session parameter debug_bing_tile_children_max_zoom_shift controls
the max difference in zoom (zoom shift) between parent bing tile and child.
The number of children scales like `4 ** zoom_shift`, so bounding this prevents
some OOMs.  In production we are finding zoom shift 7 queries running fine, so
increase this shift so they can run.
