Made parameters passed to CbmStsReco handled by the runtimeDb.

For the processing of experiment data (mCBM), the STS parameters have to be set explicitly in the run macro. Currently, they are not stored to the runtimeDb, but are just transient and thus not available for processing steps other than local STS reconstruction. This MR amends this by making the user-set parameters managed by the FairRuntimeDb, such that they are both accessible from e.g. L1 in the same run and are stored to the parameter output file.
