Minor optimization of the "abort redisplay" feature

* src/xdisp.c (init_iterator, set_iterator_to_next)
(redisplay_internal):
* src/syntax.c (scan_sexps_forward):
* src/regex-emacs.c (re_match_2_internal):
* src/bidi.c (bidi_fetch_char, bidi_paragraph_init)
(bidi_find_bracket_pairs, bidi_find_other_level_edge): Don't call
'update_redisplay_ticks' if aborting too-long redisplay is
disabled.  (Bug#45898)
