An actual use of the `BACKGROUND_X11` thread may have briefly existed in 2009 but probably never shipped; it's been unused since then, and even the comments mentioning it have been pruned (bug 909028, bug 624422). The other thread types besides IO have been commented out ever since they were first committed. This patch also removes `x11_util.h`, which has been unused since 2017 (bug 1426284); earlier in history, it had one of those comments mentioning the nonexistent X11 thread.
