Do not use UTBoardMapping
UTBoardMapping is a namespace with functions to access some global storage, thus not thread safe.
Moreover the mapping it does is non-trivial only in the case of UT with Tell1 based readout (does it even make sense?).
This MR remove the use UTBoardMapping, but it requires a matching MR in LHCb (for new features in IUTReadoutTool).
