applied Michiel's sf patch 2792742 to speed up Cairo and macosx collections

Commit Michiel de Hoon's integration of path simplification into the
Mac OS-X backend. Thanks, Michiel!

Rework the nan-handling/clipping/quantizing/simplification
framework so each is an independent part of a pipeline.
Expose the C++-implementation of all of this so it can be
used from all Python backends. Add rcParam
"path.simplify_threshold" to control the threshold of
similarity below which vertices will be removed.

apply Michiel's patch to macosx backend to fix rounding bug - closes
sf bug 2508440.
