The axes in fvar are in arbitrary order, NOT sorted. Hence have to
lsearch all entries.

Fixes https://github.com/harfbuzz/harfbuzz/issues/2743

895acdf7c7 [ci] Don’t build Cairo subproject with FontConfig on win32 cross-build 
We don’t need it and it breaks the build because FontConfig renamed its
master branch and the released version of Cairo wants to build
FontConfig from master branch.

71a6296620 [tests] Make record-test.sh work with .otf files 
It hard-codes the file extension, but fonttools sunset will use .otf for
CFF fonts, so hard-code the output file from subset as well.

bc06af977f [subset] speed up feature collection when tags are specified. 
Precompute a feature index filter to avoid needing to iterate the feature tag list for each encountered feature index. For this particular fuzzer case speeds up feature collection from 50s to 2s.
