Make slimmed code of PixelConfigCondAlg.h (ATLASRECTS-7703)

Soshi Tsuno requested to merge stsuno/athena:atlasrects-7703 into main

The PixelConditionsAlgorithms/PixelConfigCondAlg.h is getting longer and longer since the "year-depended" conditions are hardcoded in this header file as job option.

Now, such year-dependent conditions are moved into Group Area. /eos/atlas/atlascerngroupdisk/asg-calib/PixelConditionsAlgorithms/v1/

So far, the file format is very similar as what was written in the hardcoded one.

The "constant" part (not year-dependent) is also possible to move in the Group Area. But at the moment, same as before (i.e. hardcoded).
