Allow Extensions to Extend Felix OSGi Bootdelegation via Manifest.mf

Description

Currently, OSGi bootdelegation can only be modified in Lucee's source code or via environment variables, causing class loading issues in extensions that need to handle transitions between package namespaces (e.g., javax to jakarta).

Implement a mechanism allowing extensions to define additional bootdelegation packages via their Manifest.mf file through new entries:

felix-bootdelegation: For extending org.osgi.framework.bootdelegation
felix-system-packages: For extending org.osgi.framework.system.packages

Example Implementation: Current Manifest:

Manifest-Version: 1.0
Built-Date: 2025-03-24 14:19:46
version: "3.0.0.15-SNAPSHOT"
id: "3F9DFF32-B555-449D-B0EB5DB723044045"
name: Lucee WebSockets Extension
description: Websocket integration into Lucee.
start-bundles: true
release-type: server
startup-hook: "{'class':'org.lucee.extension.websocket.WebSocketEndpointFactory','name':'org.lucee.websocket.extension','version':'3.0.0.15-SNAPSHOT'}"
lucee-core-version: "5.3.0.20"

Proposed Addition:

felix-bootdelegation: "jakarta.websocket,jakarta.websocket.*"
felix-system-packages: "jakarta.websocket,jakarta.websocket.server"

Benefits:

Extensions can handle class loading for transitional APIs (javax/jakarta)
Reduces need for core modifications when adding support for new frameworks
Allows extensions to be more self-contained and control their dependencies
Prevents classloading conflicts like the WebSocket extension's current issues

Environment
