Remap landuse kinds at mid and low zooms.

[zerebubuth]

Remap kind of various landuse layer features to give better opportunity for mid and low zoom merging.

Many of the kinds specified in #1779 depend on #1781, and will have to be implemented as part of #1781 when it gets done later.

Additionally, natural=cliff is in the earth layer, not the landuse layer. Because it wouldn't be merged anyway, I left it out. I think if we want to move that to the landuse layer (which we might if we want to merge with landuse=quarry), we probably have to add that to the v2 wishlist?

Connects to #1779.

LGTM

@zerebubuth Can you run stats on the feature count of each landuse layer kind values that are present min_zoom < 13? Just want to make sure we're catching all the basic ones, and the exceptions are true landcover (like military or park).

Let's just leave cliff where it is in the earth layer (good point about SemVer and v2). I think we only bring in lines there, so it doesn't actually matter?

And so this Github PR is easier to read...

@zerebubuth responded to #1790 (comment) in #1790 (comment):

The zoom ranges in the YAML files allow residential down to zoom 4 and natural_wood / wood down to 6, and a bunch of others down to 8. Whether any are actually that large is questionable, and I'm running a query to find out - although it may take some time to run.

Additional follow-up in #1795.
