#jira UE-7808 - Editor slows exponentially when selecting an instanced static mesh in viewport that has a large number of instances
[CL 2427864 by Richard TalbotWatkin in Main branch]
The display name, filter string, and tooltips for the property editor (and associated detail customizations) are now stored as FText rather than FString. This allows us to remove SLATE_TEXT_ARGUMENT from the detail customization widgets.
