CommonLayoutWidget class

Provides its child with both CommonLayout and the breakpoint-specific RawSpacings

All RawSpacings are optional and if none is provided, it uses the default values found in SpacingsInheritedWidget.defaultSpacings. These spacings act like an auxiliar set of fields that:

• help the related code to be less prone to hardcoded values (provides type-safety with the usage of Spacing);
• alongside the provided utilities, makes handling spacings less verbose by handling the proxying the logic to this instance's resolver.

Because CommonLayoutWidget uses a LayoutBuilder to get its device constraints, no MaterialApp (or MediaQueryData) is required above/below this widget.
