Refactor FeatureGrid and AgFeatureGrid to a function component

[dnlkoch]

Description

This refactors the FeatureGrid and the AgFeatureGrid to function components (and makes use of the shared hook useOlLayer). In addition, common grid properties and variables are extracted to a commonGrid.ts file.

Breaking changes:

• map prop got removed (makes use of useMap now).
• prop columnDefs got removed, use default columns instead (inFeatureGrid)
• Bump aggrid to version 31.1 and bump required OpenLayers dependency to v9
• Remove prop types dependency
