Remove ISettingsUtils and ISettingsPath interfaces (#44331)

<!-- Enter a brief description/summary of your PR here. What does it
fix/what does it change/how was it tested (even manually, if necessary)?
-->
## Summary of the Pull Request

This PR removes the ISettingsUtils and ISettingsPath interfaces to
reduce some complexity. They only existed so the classes can be used
with moq. But this is also possible by using virtual methods which is
cleaner.
