17594	tracktype=grade2 with surface=sand is always wrong	mkoniecz	team	"==== What steps will reproduce the problem?
1. Tag `highway=track tracktype=grade2 surface=sand` 
2. Run validator

==== What is the expected result?
Validator complains that sand surface with `tractype=grade2` makes no sense

==== What happens instead?
Nothing.

==== Please provide any additional information below. Attach a screenshot if possible.
9k+ cases - see http://overpass-turbo.eu/s/HVz

It makes sense to complain also about `surface=mud`

It may happen as result someone inverting order of tracktypes or if `tracktype` and `surface` tags were added separately, maybe years apart.

It makes sense to check it everywhere where both `surface` and `tracktype` is tagged, not only on tracks. 

#17592 is a very similar one - about broader list of mismatch for `grade1`
