Acts tracker: refactor MpdTpcDetector & move away from TGeoDetector

as part of moving to v38.2.0 where all detectors inherit from ActsExamples::Detector base class

The current implementation is buggy, giving messages like:

00:47:47 LayerArrayCr ERROR Layers are overlapping at: 403.275. This should never happen. Please check your geometry description.

The tracking then can crash giving the message
