Remove landuse=wood rendering

__Pull opened for discussion__

`landuse=wood` renders the same as `natural=wood` for fill, but omits the name.

`landuse=wood` has 4.7k uses compared to 1.8 million `natural=wood` and 2.2 million
`landuse=forest`.

Are we encouraging odd non-standard tagging by rendering `landuse=wood`? If we want to keep `landuse=wood`, we should then add it to [the `natural=wood` name rules](https://github.com/gravitystorm/openstreetmap-carto/blob/v2.3.3/amenity-points.mss#L474).
