Revert "nanosvg: Sync with upstream cc6c08d"
This reverts commit f697e7879b.
Part of the update introduced a regression:
https://github.com/memononen/nanosvg/issues/188.
We could include a local revert of the problematic commit but let's just do a
full revert to our previous version, and I'll re-update once the regression
is fixed upstream.
Fixes #43641.
