Enable Oculus Quest Unity Development on OSX / macOS via `Oculus > OVR Build`

Oculus Quest Unity OSX Integration Patch

1. Install the embedded Android SDK and copy the file `adb` to `adb.exe` e.g:
```
cd /Applications/Unity/Hub/Editor/****/PlaybackEngines/AndroidPlayer/SDK/platform-tools/
cp adb adb.exe
```

2. Apply the following diff to the Oculus Integration asset.

3. Navigate to Oculus > OVR Build > OVR Scene Quick Preview

4. Click `Build and Deploy Scene`. It will ask you to build the Transition APK. If this is the first time doing show click `Yes`. In subsequent runs, it fails to detect that the APK has already been installed, thus you can click `No` which will dramatic improve the build time. Your scene needs to be saved before clicking `Build and Deploy Scene`, otherwise any changes will not be applied.
