Move detector-specific code to read the geometry database into
standalone "[Det]GeoDB.py" modules. Use this code both in the old
jobproperties as well as in the new-style `AutoConfigFlags` to avoid the
copy&paste of the same code.

Also fix the caching of `AutoConfigFlags.GetDetDescrInfo` to make sure the
geometry DB is only queried once per geometry tag.

This replicates the functionality in in MuonGMJobProperties.py

The `GetDetDescrInfo` method can be used to set the default values of
new-style flags based on information from the Detector Description Database.

The new code is based upon code from the following old-style configuration
modules:
`CommonGMJobProperties.py`, `InDetGMJobProperties.py` and `LArGMJobProperties.py`.

Local tests confirm that the `DigitizationConfigNew_test.py` CI test produces
the same output after the change.

Initial python3 port.  Not intended to be complete yet; only that required
for basic athena/configuration jobs.

- use lazy string formatting in logging calls
- some Python3 fixes
- remove print statements

Fix style and syntax errors discovered by the flake8 unit test.
