Block hgTables output for QuickLift tracks and hide QuickLift groups, refs #37519

QuickLift remaps tracks from another assembly on the fly for display,
but the underlying bigBed data is in the source assembly's coordinates,
so output queries against the destination assembly's region return no
results (or, with a whole-genome query, dump source-assembly data with
source coordinates).  Detect quickLiftUrl on the selected track and
errAbort from doTopSubmit and doSummaryStats with a clear message.
Also filter groups whose label starts with "QuickLift" out of the
Group dropdown in hgTables, and clear the cart's group var if it was
pointing at a QuickLift group.
