CI build slowdown on macos after GitHub Action runner image update

[filzrev]

Recent CI build on macos-latest takes twice as long to complete compared to other OS. (10sec -> 19sec)

It seems occurred after GitHub Action runner image are updated to macos-12 Version: 20240329.1.
If this problem persists, some sort of investigation will be required.

Note

Current CI build using macos-latest image.
So it's expected to migrate to ARM-based macos-14 image in the near future.

macos-latest default vm image changed to ARM-based.
And it seems run faster than windows/ubuntu build after changes.
