Add QPlatformTheme::MenuBarFocusOnAltPressRelease

Browse Source 
On Windows, pressing and releasing the Alt key moves focus to the
menubar. This is implemented in widgets, but not in Qt Quick.

Add a new theme hint so that we can make Qt behave natively on all
platforms, and make the common style's respective styleHint default to
the theme hint.
