Split OSM plugin from server plugin

[Andy2003]

This PR splits OpenStreetMap (OSM) functionality from the main server plugin into a separate, optional osm-server-plugin module. This architectural change allows users to optionally include OSM support by adding the OSM plugin JAR alongside the main server plugin.

Key changes:

• Created new osm-server-plugin module with OSM-specific classes, procedures, and resources
• Moved OSM classes from org.neo4j.gis.spatial.osm to org.neo4j.spatial.osm.server.plugin package
• Updated all imports, tests, and documentation to reference the new package structure
• Split META-INF service provider files between the two plugins
