To synchronize other types of event info,
Efl_Canvas_Animation_Player_Running_Event_Info is changed to
Efl_Canvas_Animation_Player_Event_Running.
Remove unused struct.
Summary:
Efl.Player interface simply provides play functions,
but another interface which indicates Efl.Player will play is also
needed.
Test Plan: Run elementary_test->Efl.Animation tests
