Update bridge levels for bright style

[AndriusGeo]

This PR fixes two major problems with Bright style:

• To fix styling issues at 3-level junctions, a level 2 bridge representation has been added;
• Bridges have been added for minor roads, which were originally missing in the Bright style (strange, because this style has, for example, a bridge for a tracks, but side roads were not included).

P.S. Positron style does not use multiple levels at all.

This looks amazing!

I highly recommend submitting a pull request for the bridges over minor roads issue to OpenMapTiles/osm-bright-gl-style. It definitely seems like a bug that needs fixing.
