Refs #10263. Adding new algorithm PoldiPeakSummary

PoldiFitPeaks1D produces a summary table with peak information. Since this will re-occur in the 2D-fit and also in version 2 of the algorithm, this is put into a separate algorithm. It's very small and it will be much easier to deal with possible changes to the output format of poldi peaks.

FitCharacteristics is gone too, this is information that could probably go into the log, but it's not necessary to have this information in an output workspace.
