[1.x] Respect `scalaOrganization` in compiler bridge resolution (#8732) (#8799)

**Problem**
`scalaOrganization` was ignored during compiler bridge resolution because `ZincLmUtil.getDefaultBridgeModule` hard-coded `ScalaArtifacts.Organization` (`org.scala-lang`).

**Solution**
Add a `scalaOrganization` parameter to `ZincLmUtil` methods, and passing `scalaOrganization` value to those methods.
