Move CI jobs with macos large runners

Running CI jobs on MacOS large runner on each pull request
is problematic for forks. These runners are not free and require
billing to setup. Therefore it makes more sense move macos-14-large
and macos-15-large into os-zoo.yml which is scheduled to run nightly.
