Revert a recent change that caused redisplay slowdown

* src/xfaces.c (recompute_basic_faces): Revert the change which
caused recalculation of all the faces, as it made cursor motion
too slow.  Reported by Juri Linkov <juri@linkov.net> (bug#72692).

(cherry picked from commit 9b299dd79c1627c7ad6b037d599a8e80a92573cd)
