Elasticsearch: Unify default value for geo hash grid precision across the code to 3 (#73922)

* Unify default value

* Use variable to keep default precisions in sync

* Use default precision variable

* Update precision description

* Update defaultPrecisionString and move

* Be more specific in naming of variabkle

* Revert "Merge remote-tracking branch 'origin' into ivana/es-precision-default-value"

This reverts commit 599f236a7717315a43434b88b50aea2fdfb502e3, reversing
changes made to 6742be0c6de6b735cf4a0b82143bc628a7622d87.
