They replace the existing Extbase Signal Slots in the File Abstraction Layer.

## Impact

All existing signals and their registered slots will work exactly the same as before, however
it is highly encouraged to migrate to the new PSR-14 based events.

In addition, all Core hooks using these events have been migrated to new PSR-14 events,
all new Events have a description when to use them and what the benefits are.

The Event `AfterFileCopiedEvent` in addition also contains the newly created File
object.

Have a look at the new PHP classes to understand the Events and to learn more about PSR-14.
