Fix the issue that context menu doesn't show on fullscreen Pepper Flash.

- generate WebInputEvent::ContextMenu events.
- calculate the context menu position correctly.
- monitor mouse down events on fullscreen render widget, so that we can pass correct timestamp to gtk_menu_popup.

BUG=None.
TEST=Open a fullscreen Youtube video, and right click on it to see whether context menu shows up or not.
