Updated V0 config to fix IDTR2

This MR aims at providing a more central implementation of the Reco_V0Finder configuration, to fix in particular the IDTR2 configuration

The IDTR2 configuration was not setting in particular the V0Tools property of the V0MainDecorator. To make maintenance easier, the configuration of the relevant tools is provided centrally and used in BPHY10, BPHY24, FTAG1 and IDTR2 configs. This was checked to leave unchanged the outputs and to fix the IDTR2 derivation.
