Drop the hand-built Files column from the TSS faceted tables. refs #35528

UCSC will generate the download links in the faceted table, so the Files column
each composite built for itself is redundant. Remove downloadCell, the Files
header and cell, the Files entry in subtrackUrls, and the DOWNLOAD constant that
only fed them. The table is now Tissue, Sample class, Experiment, Cell line on
all three composites. writeMetadata no longer needs db or track; the metadata
files it writes are byte-identical.

Lead each Data Access section with the link to the hgdownload directory, since
that is now the way to a single file, and keep the naming convention beside it.
Drop the paragraph describing the Files column.
