Fix T102532: bevel spikes with loop slide.

There's a compromise of a code parameter called BEVEL_GOOD_ANGLE,
and bugs T44961, T86768, T95335, and this one, are all about problems
with various values of that parameter. If an angle of an adjacent
non-beveled edge is too close to that of the beveled edge, then you
get spikes. The BEVEL_GOOD_ANGLE says that if you are within that
angle difference, then no bevel happens. If the value is too small
then one gets spikes for certain models people build; if the value
is too large, then other people are annoyed that no bevel happens.
Hopefully this compromise in this commit is the final one I will do
before switching to Bevel v2, where none of this should be an issue.
