Remove duplicate click event in simulate_mouse_click (#36957)

After `InputEvent::Touch` processed by Script, it sends
`TouchEventProcessed` back to Constellation, which goes through hit-test
etc. and loops back to Script again. However,
`WebViewRenderer::simulate_mouse_click` should not send
`MouseButtonAction::Click` due to #36413

Testing: Manually tested by converting mouse to touch
