remove the bigBedOnePath fallback, leaving a single bigBed load path, refs #36940

bigBedOnePath has defaulted to on since v492 and the setting has been removed
from the hg.conf of the RR, Euro, Asia and hgwbeta.  Drop the check and the code
it guarded at all four sites: the field-count default in
bigBedAddLinkedFeaturesFromExt, the method setup in commonBigBedMethods, the
bedSize default in bigBedClick, and the bigBed case in hgc.  The two branches in
the hgc case differed only in a minimum the surviving path does not want.

complexBedMethods lost its only isBigBed=TRUE caller with that branch, so drop
the parameter.

Retire the setting from the hg.conf catalog and its gate backlog, and repair the
two hgc.c citations whose line numbers this commit shifted, refs #37925.

Verified pixel-identical: 14 scenarios rendered before and after, covering the
four QA sessions on the ticket plus mm10 knownGene, dbSnp155, rmsk,
encRegTfbsClustered, clinvar and tandemDups.  All AE=0.
