Fix platform dependent compilation for OSX

[bclausdorff]

There are code blocks wrapped by UNITY_STANDALONE_OSX to only work on OSX.
But to make them also work in the Unity Editor on macOS, a check for UNITY_EDITOR_OSX needs to be added as well.

1. Filter quick link section from too many macOS drives

2. Documents quick link should lead into actual ~/Documents folder

3. Add user folder to quick link section

Apologies.

It works with UNITY_STANDALONE_OSX alone when one has set the platform to macOS in the Build Settings.

I think your fix is still valid because as you've demonstrated, the plugin doesn't work properly when target platform isn't set to macOS in OSX editor.

You're right. The behaviour is unexpected in the Editor. Thank you. I'm reopening the PR. :)

So whether #if UNITY_STANDALONE_OSX is true depends only on which target platform is set in the Build Settings (regardless of which platform the Editor is running on).

Which means that it will also be true when setting macOS as the build target on a Windows machine.
Which itself is leading to buggy Quick Links on Windows.

This behaviour already exists on the current main branch.
I will adjust the PR to also fix these as well.

Windows Build Target on Windows

Is unaffected of the changes and looks as expected.

@yasirkula
I squashed a fix for Windows into the existing commit.
Please have another look. :)

Awesome! I got sick this week, hence the delay 😞
