refactor: RM IEventQueueBuffer::newTimer and IEventQueueBuffer::deleteTimer

port: https://github.com/input-leap/input-leap/pull/1592
Original Message:
  base: Remove IEventQueueBuffor newTimer and deleteTimer APIs
        In the current implementation timers are not platform-specific. On all
        currently supported platforms timer constrution and destruction is
        simple new and delete, so it does not make sense having this
        customization point.
