Create VM GC agent and common bundles
This commit extracts VM GC data collection from SystemBackend and related
classes to a vm-gc-agent bundle. It also moves the VmGcStatDAO from
common-core to a vm-gc-common bundle that registers the DAO once Storage
is available. This also removes the DAO from DAOFactory.
