refactor: pinning window won't set CanJoinAllSpaces on macOS (#854)

This commit reverts the logic introduced in
e7dd27c744:

> Pinning the main window would bring "NSWindowCollectionBehaviorCanJoinAllSpaces"
> back to make it really stay pinned across all the spaces.

Commit 6bc78b41ef (diff-b55e9c1de63ea370ce736826e4dea5685bfa3992d8dee58427337e68b71a1fc1)
did a tiny refactor to the frontend code merged in the above commit,
these changes are reverted as well.

We revert these changes because we observed an issue with window
focus, and we don't know the root cause and how to fix the issue either.

The following change is kept because we don't want to hit this NS panel
bug[1].  But if the issue still exists after this commit, it will
be removed as well.

In "src-tauri/src/setup/mac.rs":

```diff
 panel.set_collection_behaviour(
-       NSWindowCollectionBehavior::NSWindowCollectionBehaviorCanJoinAllSpaces
+       NSWindowCollectionBehavior::NSWindowCollectionBehaviorMoveToActiveSpace
```
