Add singleCellSignalsPeaks track to hg38

Native faceted composite built from the per-cell-type signal (bigWig) and
peak (bigBed/bigNarrowPeak) tracks of the UCSC Cell Browser single-cell ATAC
datasets, re-parented under one track in the regulation group. 936 subtracks
across 9 datasets. Data files live in
/hive/data/genomes/hg38/bed/singleCellSignalsPeaks and are served via a
/gbdb/hg38/bbi symlink; the .ra is regenerated from the Cell Browser hub build
by makeDb/scripts/singleCellSignalsPeaks/makeSingleCellSignalsPeaksRa.py.
