Add Scala Native build for jsoniter

[kyri-petrou]

Resolves #1795 . This PR adds support Scala Native support for the jsoniter module. One caveat of this is that jsoniter-scala added support for SN in 2.17.4+, and these versions are not published for Scala 2.11. Are we happy to stop publishing Scala 2.11 versions of the jsoniter (JVM) module, or should we use the old version for JVM and the latest for JS / Native?

I'll create a PR to master to port these changes to master as well once this one has been approved

The build failures are due to sbt/sbt#7202, so we're waiting to see what's up with JFrog :)

Issue seems to be marked as resolved now. @adamw should I push an empty commit to trigger the builds or are you happy to restart it?

Unrelated to this PR, but I noticed the following warning when building Scala 3 modules:

Bad option '-target:jvm-11' was ignored

With Scala 2.13 I get the following warning:

-target is deprecated: Use -release instead to compile against the correct platform API.

Should that flag be changed to -release:11 instead (which also works with Scala 3)? I can make the change in this PR or open this as a separate issue / PR if it's an issue

Ok seems to be fixed now - thanks :)

As for the build flags - yeah, some cleanup is needed to adjust them for the specific versions. If you'd have the time to work on that, would be most appreciated :)

v3 release in progress

[kyri-petrou]

If you'd have the time to work on that, would be most appreciated :)

Can do 👍. Do you think it's worth cleaning up both v3 and v4 or shall we just focus on v4?

[adamw]

I think I'd focus on v4 :)
