MTD geometry: update tests for DD4hep

[fabiocos]

PR description:

This PR contains a collection of updates to support the validation of DD4hep in standard workflows, beyond the pure dump of geometry objects:

• update and add mtd-devoted DD4hep ideal configurations based now on the complete ones, commenting all subdetectors but MTD and using an ad-hoc empty tracker mother volume;

• update the DDD ideal geometry dump, to get back namespaces in the path dump (for easier comparison with DD4hep);

• add a customization fragment to SimG4Core/PrintGeomInfo to easily use in any configuration the PrintGeomInfo class (the existing code is more an ad-hoc standalone configuration).

PR validation:

By manually adapting the existing DD4hep test workflows to use the MTD-only geometry, the step1 may run, cross MTD (as verified with SteppingVerbosity) and produce SimHits within MTD in MtdSD, as visualized with runSimHitCaloHitDumper_cfg.py.

The issues causing crashes within step1 for Phase2 test workflows are not due to MTD according to this check, they come from the geometry building in DD4hep_DDG4Builder when the whole configuration is used.

@kpedro88 @silviodonato @qliphy do you see a problem with this PR?

[kpedro88]

@fabiocos is it necessary to retain non-MTD subdetectors as commented-out lines in the xml, rather than removing them completely?

[fabiocos]

@kpedro88 this is for simplicity to compare in a straightforward way with the original from which this is derived. It is not strictly speaking necessary, it makes the comparison a bit simpler, and as it is a test configuration that will go as soon as dd4hep migration is completed I do not think it should create problems

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
