Project validation stage 2

[parisacognitive3d]

Description

This PR addresses bugs and introduces new validation items in the project validation window:

• Introduced a new validation item to check the status of ForceRemoveInternetPermission in the OpenXR Meta Quest support feature.
• To address inaccessible variables due to their protection level, Reflection was used for OpenXR versions 1.8.1 and 1.8.2, where ForceRemoveInternetPermission was first introduced.
• Added validation items for PXR_Managerand OVRManager components to verify their presence in the scene.
• Resolved a bug where Project Validation failed to apply floor tracking mode recommendations. This was fixed by defining local variables separately in fixAction and checkAction.
• Fixed a compile error in Unity 2019 (with .NET Standard 2.0 or NET 4.x) by renaming variable names.
• Implemented the capability for developers to toggle the display of the validation popup before building an app, which can be accessed under additional settings in the project validation window.
