Cut tube segment dd4hep conversion tests

Proposed labels: Improvement, Needs Discussion

Proposed next steps on cut tube support that touch the Acts code base:

1) Extend TGeoTubeConversionTests.cpp with a TGeoCtub (like done [here](https://github.com/acts-project/acts/blob/main/Tests/UnitTests/Plugins/TGeo/TGeoTubeConversionTests.cpp#L64) for TGeoTubeSeg), this test will fail until support below is added,

a) Extend Acts::TGeoSurfaceConverter::cylinderComponents (like done [here](https://github.com/acts-project/acts/blob/main/Plugins/TGeo/src/TGeoSurfaceConverter.cpp#L88)
for TGeoTubeSeg) to support TGeoCtub (TGeoCtub inherits TGeoTubeSeg inherits TGeoTube, so
the same strategy taken there simply extends), and similarly extends
Acts::TGeoSurfaceConverter::discComponents (like [here](https://github.com/acts-project/acts/blob/main/Plugins/TGeo/src/TGeoSurfaceConverter.cpp#L240))
The test above should now succeed.

2) extend Acts::DD4hepLayerBuilder::endcapLayers (like done [here](https://github.com/acts-project/acts/blob/main/Plugins/DD4hep/src/DD4hepLayerBuilder.cpp#L90) for TGeoTubeSeg) and Acts::DD4hepLayerBuilder::centralLayers (like done [here](https://github.com/acts-project/acts/blob/main/Plugins/DD4hep/src/DD4hepLayerBuilder.cpp#L238) for TGeoTubeSeg) to support TGeoCtub.

3) Are there any DD4hep unit tests that should be updated to test?
