yuzu-qt: Attempt to workaround broken Vulkan installations
This does a few things in order to make the default setting Vulkan
workable.
- When yuzu boots, it just opens the Vulkan library.
- If it works, all good and we continue with Vulkan as the default.
- If something breaks, a new file in the config directory will be left
behind (this is deleted normally).
- If Vulkan is not working, has_broken_vulkan is set to true.
- The first time this happens, a warning is displayed to notify the
user.
- This forces use of OpenGL, and Vulkan cannot be selected.
- The Shader Backend selector is made accessible for use in custom
configurations.
- To disable has_broken_vulkan, the user needs to press a button in
Graphics Configuration to manually run the Vulkan device
enumeration.
