Qt Quick Layouts: Alias between "gap" and "spacing"

The new FlexBoxLayout type has a gap/columnGap/rowGap property: https://doc-snapshots.qt.io/qt6-6.10/qml-qtquick-layouts-flexboxlayout.html#gap-prop

While this is consistent with W3C naming (https://www.w3.org/TR/css-align-3/#gaps), it is unfortunately inconsistent with our existing spacing/columnSpacing/rowSpacing API used by other Layouts (https://doc.qt.io/qt-6/qml-qtquick-layouts-columnlayout.html#spacing-prop) and even by Widgets(https://doc.qt.io/qt-6/qlayout.html#spacing-prop)

Should we provide an alias to map gap <-> spacing?
