Add support of multiple native outputs

[pomadchin]

This PR modifies all build tools behavior to put all the possible project outputs into the res artifact.

See https://github.com/sbt/sbt-jni/issues/185#issuecomment-1832150228

Closes https://github.com/sbt/sbt-jni/issues/185

@datben could you check if it works for you?

I'll try it on my repos as well later to ensure that nothing is broken with this change.

I tested it on a project https://github.com/datben/jni-test, as the result it puts two binaries into the jar. The behavior looks legit!

@pomadchin how can i add this branch in my sbt plugin, i tried this : addSbtPlugin("com.github.sbt" % "sbt-jni" % "1.6.0+40-911e3587-SNAPSHOT" from "https://github.com/sbt/sbt-jni.git#feature/list-files") but it doesnt work (i am not very familiar with sbt plugins)

[pomadchin]

@datben we don't not push to artifactory from branches; the easiest way to test like any scala project: clone, checkout branch, sbt publishLocal => use the published version (bump version up in the plugins.sbt file)

$ git clone git@github.com:sbt/sbt-jni.git; cd sbt-jnil; git checkout feature/list-files
$ sbt publishLocal
# bump plugin version here https://github.com/datben/jni-test/blob/master/project/plugins.sbt#L1

@pomadchin lIt looks fine on my side, but perhaps you could consider adding a parameter to allow or disallow multiple outputs (defaulting to false) to avoid it being potentially a breaking change

@datben makes sense :+1:

Added a new key:

nativeMultipleOutputs := {false | true} // false by default
