Fix errors caused by DD4Hep future upgrades refactor

This merge request fixes the errors caused by Detector!428 (merged). This is mostly done by replacing all instances of trunk with run3/trunk and equivalent.

This merge request is part of the larger 'detector refactoring for future simulation' task, and these set of merge requests are expected to come in together. See LHCb!4283 (merged) for which merge requests come together in the stack.

DaVinci specific notes

This may require a reference update, as I have purposely left any file with .ref alone.

TODO

• Add Patrick's suggestion to LHCb
• Check for any more trunk -> run3/trunk
• Understand why the CI test fails
