Introduce two classes to build the muon geometry from "newDD" sqlite inputs.

Two new classes (MuonDetectorFactoryLite and MuonChamberLite) are introduced to enable the construction of the Muon geometry from an sqlite file; this is a development that aims at a revised detector description infrastructure for Run 4.

These classes are not activated in any production job today; they are only switched on if/when the geometry is restored from the sqlite file; today this is only done by developers (by setting options in GeoModelSvc).

The MuonDetectorTool and the MuonDetectorCondAlg are modified to accomodate a small interface change, and (MuonDetectorTool) to activate the "Lite" classes according to the configuration of GeoModelSvc.
