Support resolving annotations for Kotlin's properties

[komu]

When an annotation is directly specified for a property defined in Kotlin constructor, Apina does not find it. For example:

class Foo(val bar: String, @JsonIgnore val baz: String)

as a workaround, one can force the annotation for the getter:

class Foo(val bar: String, @get:JsonIgnore val baz: String)

Jackson itself supports the first form, and Apina should do support that as well. It's somewhat unclear where the annotation ends up in the bytecode and how it can be associated with the property, but it probably involves parsing Kotlin's own class metadata with kotlinx-metadata-jvm.
