Add QTEST_QUICKCONTROLS_MAIN()

By default, repeat the auto tests with all available styles:

	$ ./tst_qquickmenubar
	********* Start testing of tst_QQuickMenuBar *********
	Config: Using QtTest library 5.10.0, Qt 5.10.0 (...)
	PASS   : tst_QQuickMenuBar::Default::initTestCase()
	PASS   : tst_QQuickMenuBar::Default::example()
	PASS   : tst_QQuickMenuBar::Default::cleanupTestCase()
        [...]
	PASS   : tst_QQuickMenuBar::Universal::initTestCase()
	PASS   : tst_QQuickMenuBar::Universal::example()
	PASS   : tst_QQuickMenuBar::Universal::cleanupTestCase()
	Totals: 12 passed, 0 failed, 0 skipped, 0 blacklisted, 2215ms
	********* Finished testing of tst_QQuickMenuBar *********

When explicitly specified, run only with that one style:

	$ ./tst_qquickmenubar -style material
	********* Start testing of tst_QQuickMenuBar *********
	Config: Using QtTest library 5.10.0, Qt 5.10.0 (...)
	PASS   : tst_QQuickMenuBar::Material::initTestCase()
	PASS   : tst_QQuickMenuBar::Material::example()
	PASS   : tst_QQuickMenuBar::Material::cleanupTestCase()
	Totals: 3 passed, 0 failed, 0 skipped, 0 blacklisted, 984ms
	********* Finished testing of tst_QQuickMenuBar *********
