Fix paths and tracks in transportation layer z12 and z13 (#1334)

Browse Source 
This PR fixes a bug that causes that `track` lines disappear at z13. This bug was introduced in https://github.com/openmaptiles/openmaptiles/pull/1190, which adds rendering of paths and tracks at z12 and z13.

Before this PR:
z12: lines with `route_rank = 1` are added (no matter what `highway`).
z13: lines with `route_rank BETWEEN 1 AND 2` and `highway = 'path'` are added.
-> tracks with `route_rank=1` are added at z12 but not at z13.

After this PR
z12: lines with `route_rank = 1` and `highway IN ('path', 'track')` are added.
z13: lines with `route_rank BETWEEN 1 AND 2` and `highway IN ('path', 'track')` are added .
-> only tracks and paths are added at z12 and z13 (which was IMHO the goal of https://github.com/openmaptiles/openmaptiles/pull/1190)

* Add only the most important paths and tracks (route_rank=1) to z12 and more important ones (route_rank between 1-2 or sac_scale or has name) to z13.
