Mark MappingTarget as #[non_exhaustive] for increased semver flexibility

Browse Source 
This will allow us to add new enum variants in the future without breaking
semver compatibility. See
https://doc.rust-lang.org/reference/attributes/type_system.html#the-non_exhaustive-attribute

Since we already added an enum variant since v0.18.3, now is a good time to mark
it as `#[non_exhaustive]`.
