Windows standalone build profile shows Android 'Offscreen Rendering Only" project validation warning.

Description:

When the Android/Meta Quest/Android XR build platform OpenXR setting "Offscreen Rendering Only (Vulkan)" is checked, it generates a validation warning for the Windows Standalone build profile - but It should only generate the validation warning and fix option for Android build profile.

Steps to reproduce:

1. Create a new LTS VR Core template project, leave it on the default Windows Standalone build profile.
2. If it isn't checked, go to Project Settings > XR Plug-in Management > OpenXR and click on the Android, Meta Quest, Android XR tab. Then check in the box right above where you set the Enabled Interaction Profile - "Offscreen Rendering Only (Vulkan)"
3. Enable the Mock HMD Loader checkbox on Project Settings > XR Plug-in Management.
4. Click on Project Settings > XR Plug-in Management > Project Validation and look at both the Windows Standalone tab and the Android tab.

Actual results: 

Both Windows and Android Project Validations show the warning and fix.

[OpenXR] When OpenXR loader is enabled and the OpenXR setting 'Offscreen Rendering Only (Vulkan)' is checked then main display is disabled on all Android platforms.

Expected results: 

Only the Android tab should show this validation warning, as it is a setting specific to that build profile.

Reproducible with versions: 

1.16.0

Not reproducible with versions: 

Have not tested with old OpenXR versions yet. This is a low priority bug, but if we want to fix it and it requires checking older versions for the same issue I can preform that work at that time this bug has been approved for fixing.

Can’t test with versions: 

N/A see note above.

Tested on (OS): 

Windows 11
