Small enhancements to geometry DB payload validation scripts

[cvuosalo]

runDDDvsDBGeometryValidation.sh compares new geometry DB payloads with the geometry XML files and the payloads in the Conditions DB. It will show differences down to the level of |1.e-23|. This PR adds the option to reduce the precision of comparison to |1.e-7| to allow focusing on big differences without being overwhelmed with tiny numerical fluctuations.
Also, values in simulation geometry that are shown to four decimal places are rounded to zero if they are < |5.e-5| to avoid showing differences between 0.0000 and -0.0000, which are not very helpful.

These scripts are for expert use and have no effect on production workflows.

No backport is needed.
