`aem.events_osgi_mapping` allow osgi application events based on a configuration value

allow osgi application events based on a configuration value

add the following https://github.com/adobe/aio-lib-java/blob/main/aem/events_osgi_mapping/src/main/java/com/adobe/aio/aem/event/osgimapping/ocd/OsgiEventMappingConfig.java

```
@AttributeDefinition(name = "Allow OSGI Application Events",
description = "true/false to allow or disallow application triggered osgi events")
String osgi_allow_application_events() default false;
```

and refactor https://github.com/adobe/aio-lib-java/blob/main/aem/events_osgi_mapping/src/main/java/com/adobe/aio/aem/event/osgimapping/eventhandler/AdobeIoEventHandler.java#L69

to take the above new conf into consideration

先从 OsgiEventMappingConfig.java 开始，了解现有的配置模式，然后检查 AdobeIoEventHandler.java 第 69 行附近处理应用程序触发的 OSGI 事件的代码。添加配置值，并验证 handler 是否根据该值允许或拒绝应用程序事件。
