Add detector type_flags to subsystems

[wdconinc]

Is your feature request related to a problem? Please describe.
DD4hep expects detectors to have a <type_flags> definition in the compact file. This can be used to determine if e.g. an event had any hits in a tracker or to disable or enable all calorimeters (though we don't actively use this in CI or production). In theory, we could use the DetectorSelector mechanism to enable only trackers instead of defining our tracking_only.xml geometry.

However, not every detector sets these flags. Only (some of the) trackers do. This is some of the output of dumpdetector $DETECTOR_PATH/$DETECTOR_CONFIG.xml:

Describe the solution you'd like
Someone should go through and enable the appropriate flags.

Describe alternatives you've considered
This is low priority, so the alternative is to leave this alone.
