QML: Remove internal field padding from QQuickAnchorPrivate.
Don't store QQuickAnchorLine, but store both fields separately in
QQuickAnchorPrivate. This prevents padding of QQuickAnchorLine, saving
48 bytes on x86_64 (or any platform where structs are 8-byte aligned).
On x86_64, this also removes ~180 instructions for each QQuickAnchor
creation/removal, and speeds up the constructor by 25%.
While in the neighborhood, do a drive-by change and merge
QQuickAnchorLine::AnchorLine and QQuickAnchors::Anchor by removing the
former.
