b031b7910d [ci] Split out native fuzz jobs for macOS and windows (dergoegge)
Pull request description:
Split out two new CI jobs (for native macOS and windows) that run the fuzz tests on the qa-assets input corpora.
In both jobs the fuzz binary is built with `-DBUILD_FOR_FUZZING` to enable `Assume` assertions as well as `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION`.
