[collect_glyphs] Bail if input data looks like garbage
...
Specificaly, when a range or sorted array has unexpected order, we take that as
font data being garbage and bail out. This fixes significant slowdown on a bad
version of Chandas font which has a 600KB GPOS with garbage inside.
Later on, I like to add a maximum-work counter for collect_glyphs to protect
against malicious fonts as well.

Not optimized to use sortedness yet. Also start putting in place infra

A version of Chandas.ttf found on some Chrome bots has 660kb of GPOS,
mostly junk. That is causing 48 million of set->add() calls in
collect_glyphs(), which is insane.
In the upcoming commits, I'll be speeding that up by optimizing
add_sorted_array(), while also reducing work by rejecting out-of-sort
arrays quickly and propagate the rejection.
