There was a problem hiding this comment.
I'd kinda want to do one guard for the environment like we did elsewhere but this is minor, let's revisit holistically someday 👍

Adds support for importing non-escaping closures that only handle primitive types supported by
JavaKit.Just like FFM, each closure is imported as an
@FunctionalInterfacethat gets passed down to JNI. Then we call the apply method using JNI.
