New Buffer API Frontend Classes

- Switch QAbstractAttribute and QAbstractBuffer to QNode subclasses
- Get rid of all shared pointer when dealing with these (needed to expose to
  QML and use the QObject ownership)
- Introduce QGeometryRender, QGeometry, QAttributeProvider,
  QAttributeAggregator.

A QMesh component now is:
a QGeometryRenderer which specifies its QGeometry.
The QGeometry refererences n attributes. Each attribute references a QAbstractBuffer.
