CAMEL-22290, CAMEL-22289: Remove deprecated camel-cloud and serviceCa…

[sandeepGenz]

Description

This PR addresses the removal of the deprecated camel-cloud and camel-service components, as well as the serviceCall EIP. These were deprecated in Camel 3.19.0 / 4.7.0 and are now being removed post-4.18 LTS as planned.

Key Changes:

• Core Deletion: Removed core/camel-cloud and components/camel-service.
• EIP Cleanup: Removed serviceCall and related configurations from camel-core-model and camel-core-reifier.
• API Cleanup: Removed cloud-related interfaces from camel-api.
• Component Sweep: Cleaned up cloud-specific sub-packages in kubernetes, consul, zookeeper, dns, http, netty-http, and undertow.
• DSL Synchronization: Ran ./etc/scripts/regen.sh to purge serviceCall from the Java, XML, and YAML DSLs and the Camel Catalog.
• JAXB Fix: Resolved a critical JAXB binder creation failure by removing a hardcoded stale package reference in Constants.java.

Verification:

• Successfully ran mvn clean install on the affected modules: camel-core-model, camel-xml-jaxb, and camel-spring-xml.
• Verified via javap that the DefaultModelJAXBContextFactory bytecode is free of stale package references.
• Confirmed a clean git status after running the full regen.sh synchronization script.
