BCM' GeoModelXml

This MR is introducing a set of classes necessary to build the BCM' geometry in the GeoModelXml: BCMPrimeDetectorTool, BCMPrimeDetectorFactory, BCMPrimeGmxInterface and BCMPrimeOptions. This structure is following the model of ITk pixel and strip.

In addition, BCMPrimeDetectorManager is introduced for handling of the BCM' alignment transforms, which will be implemented in the future. BCM_RDO_Collection is a simple DataVector and is therefore not using any identifier scheme (not an Identifiable collection). This is the reason why dedicated implementations of other readout geometry classes (detector element, detector design) have not been provided.
