[Maps] prepare for geotile_grid aggregation (#29461)

* rename geohashgrid to geo_grid

* more stuff

* simplify getSearchFitlers

* rename precision to geogridPrecision

* missed one rename precision to geogridPrecision

* rename funtional test

* fix functional test gis/index import

* fix regression
