[ui/public/utils] Move items into ui/vis

[lukeelmers]

Part of #51560

There are a few utils in src/legacy/ui/public/utils that are primarily used by ui/vis. We should move these into ui/vis so that they can eventually be migrated along with the rest of that module.

• decode_geo_hash 👉ui/vis (and update import of geoHashColumns into agg_types) @alexwizp [[ui/public/utils] Move items into ui/vis #52615]
• range 👉ui/vis/editors/default @alexwizp [[ui/public/utils] Move items into ui/vis #52615]
• zoom_to_precision 👉ui/vis/map @alexwizp [[ui/public/utils] Move items into ui/vis #52615]
• Double check that any relevant tests are moved as well
• Document changes[0] in the ui/public cleanup section of the dev docs issue Dev Docs entry: ui/public & angular cleanup 7.6 #43511

[0] Let's document all of these as "deprecated" until we know which (if any) we want to expose in new platform contracts.
