Detect suspicious use of `Enum.valueOf`

[jzbrooks]

Enum.valueOf shouldn't be called using an Enum.name property. Since the name of the enum variants may change over time, this might constitute a runtime-only error. This is most suspicious when a different enum's name is being used as the argument. e.g.

val model = CarModel.CIVIC
val make = CarMake.valueOf(model.name)

Dealing with the enum variants more directly (like switching on the enum variant) comes with more compile-time guarantees (especially in Kotlin). Conversion between enums with similar variants should happen with these switching constructs rather than depending on the similarity of enum variant names.
