configure.ac: disable native-fiber for MinGW

because it had already been SEGV-ed in pull request'S CI
https://ci.appveyor.com/project/ruby/ruby/builds/20427065/job/32oahrcd58b8ubb1
and has never worked on trunk either.

Please make sure it does not SEGVs on your MinGW environment or pull
request before enabling native fiber on MinGW.

appveyor.yml: reverted commits to make CI green with native fiber
test/excludes/_appveyor/msys2/TestArray.rb: ditto
test/excludes/_appveyor/msys2/TestEnumerable.rb: ditto
test/excludes/_appveyor/vs/TestArray.rb: ditto
