Stop using SWTEventListener internally and mark it as deprecated

forRemoval

As it:
* is internal
* makes api tools fail thanks to it
* serves no purpose since SWT no longer runs on Java ME

Internally SWT is moved to use java.util.EventListener and as it's the
superclass of SWTEventListener makes all the APIs that taken
SWTEventListener to keep working.
