Add auto tests for MultipleMouseClickHelper

Qt WebEngine implements a custom handler for multiple mouse clicks.
These tests are intended to test whether the mouse click events are
properly forwarded to the Chromium's RenderWidgetHost.
Custom mouse click test functions have been also added for the custom
mouse click handler.
