Validation layers: crash when a username is cyrillic on Windows.

In Vulkan utility libraries repository there is `FindSettingsFile` (src/layer/layer_settings_manager.cpp) function that looks for `vk_layer_settings.txt` file. But at it checks (in order) machine's folders and then the user space's. So, the bug happens if you have a cyrillic username (on Windows) with some conditions (that I don't know because Blender works fine while debug Flax engine's editor crashes in vkCreateInstance).

Steps to reproduce:
1. Download https://github.com/flaxengine/flaxengine and https://github.com/FlaxEngine/FlaxSamples.
2. Build the debug editor.
3. Run the editor with `-vulkan -std` flags.
4. Open the `GraphicsFeaturesTour` folder and choose its `.flaxproj` file.
5. The app crashes.

Stack trace:

Solution I've found:
Run the app in the admin terminal. It makes VVL check only machine's folders avoiding the user space.
