[Tizen] (Vector) Use one EventThreadCallback

EventThreadCallback uses an fd internally and some systems have a limit on the number of fd.
So reduce the number of fd

(Vector) Erase all EventThreadCallbacks with same pointer

Due to some logical issue, there might be happend that we apply multiple
EventThread callback into VectorAnimationThread.

And if VectorAnimationTask destructor called, we remove only single callback.

If error case occured, EventThread can execute dead callback.

(Vector) Use mutex instead of ConditionalWait for EventhThreadCallback

Since worker thread can call AddEventTriggerCallback freely,

we should make some lock between workerthread and
main thread(RemoveEventTriggerCallbacks, GetNextEventCallback, ~VectorAnimationThread).

ConditionalWait used only for AsyncTask rasterization, and sleep thread.
We'd better seperate those job locker.
