Improve file watcher for macOS

[Jolg42]

We already did the improvement for Windows and Linux (see PR) but not for macOS where it would need some specific logic.

For Windows and Linux we switched completely to the new file watcher, because the old one was broken we are now watching the artifact created by prisma generate.

For macOS the "old" file watcher is still used and working, the suggestion would be to also watch the generate artifact on top of that so the people using older versions of Prisma won't have to downgrade their Prisma VS Code extension version to make it work again.

The code is here
