fix: Game settings config overrides not working properly

[ferafiks]

PR Details

Currently there is an issue with using config overrides, where the Specific Filter field doesn't actually do anything. This is because PlatformConfiguration has two static fields that are never set which are used to determine the user's graphics card and cpu model.

This PR fixes this and changes some of the logic that is used when choosing the correct configuration:

• Specific filter can now be used to filter the gpu, but not the cpu because I'm not sure if Stride even stores that property anywhere.
• Configuration overrides are now prioritized from last to first, so that the behavior is more intuitive.
• Overrides with specific filters remain prioritized over those without one.

Sidenote, this feature is extremely useless. Aside from setting a different graphics level, there is almost never a need to use a different config based on the user's platform or gpu. However, this might change in the future if the configurations will contain other settings, so maybe it's not a bad idea to keep this feature.
