Bug 302171 - Characters requiring <Alt Gr> cannot be generated using

Display.post(Event)

1) Added SWT.ALT_GR constant mapping to ISO_Level3_Shift (0xfe03).

2) Replaced OS.XTestFakeKeyEvent in Display.post, which only supported
US keyboards, with gdk_test_simulate_key to simulate key event. Added
the option to send key modifier together with key character in a single
event to Display.post on GTK.
