[Fedik]

Implementing Event classes for Module events.
The pr depend from #41226

Affected events:

• onRenderModule
• onAfterRenderModule
• onAfterRenderModules
• onPrepareModuleList
• onAfterModuleList
• onAfterCleanModuleList

Backward compatibility break (not critical):

Affects onAfterRenderModules.
Because its is imposible to pass the event attribute by reference the event listener now should use
$event->getContent() and $event->setContent($content) when need to modify the output.
