[kotlin][client] Add Jackson to interface properties and remove extra line feed (#5459)

* [kotlin][client] Ensure Jackson annotations are consistent with interface vars

* [kotlin][client] Rebuild samples

* [kotlin][client] Some kotlin client enhancements

- Don't use JsonFormat for Date objects, this should be controlled via
  a custom serializer/deserializer or a turning on and off serialization
  features of Jackson.  I've updated the jacksonObjectMapper config to
  write the dates as strings, which I think was intended in the original
  commit.
  https://fasterxml.github.io/jackson-databind/javadoc/2.6/com/fasterxml/jackson/databind/SerializationFeature.html#WRITE_DATES_AS_TIMESTAMPS
  https://fasterxml.github.io/jackson-databind/javadoc/2.6/com/fasterxml/jackson/databind/cfg/MapperConfig.html#getDateFormat--
- Dont' use @JsonFormat(shape = JsonFormat.Shape.OBJECT) for enums.
  This causes Enums to be formatted as objects with an internal "value"
  field.  In reality, OpenAPI enums are just strings without properties
  and should be treated as a string.
  https://www.baeldung.com/jackson-serialize-enums#2-enum-as-json-object
- Add's Kotlin use site annotation @get: to JsonProperty for parent interface
  properties.  Otherwise Kotlin will warn:
  "This annotation is not applicable to target 'member property without
  backing field or delegate'"
- Add's JsonTypeInfo annotations to interfaces for inheritance.  This
  was copied verbatim from the kotlin-spring generator.
