Avoid aborts in GC due to abort_on_gc

* src/lisp.h:
* src/print.c (Fprin1_to_string):
* src/eval.c (signal_or_quit):
* src/alloc.c (garbage_collect_1): Remove declarations, setting,
and testing the value of abort_on_gc.  It is no longer needed, and
using it causes rare aborts in GC for no good reason.  (Bug#23912)
