package/qt6/qt6base: allow selecting the host print support module

According to configure.cmake print support requires us to select the
widgets feature:

...
qt_feature("printsupport" PRIVATE
    LABEL "Qt PrintSupport"
    CONDITION QT_FEATURE_widgets
    SECTION "Module"
    PURPOSE "Provides the Qt PrintSupport module."
)
...

And further, according to configure.cmake, widgets requires us to select
the gui feature:

...
qt_feature("widgets" PRIVATE
    LABEL "Qt Widgets"
    AUTODETECT NOT TVOS AND NOT WATCHOS
    CONDITION QT_FEATURE_gui
)
...
