[scala] Support for Set when array has uniqueItems=true (#4926)

* [scala] Set support for unique arrays

This includes and builds upon community contribution for better Set support in Scala.
It makes property + model work as expected with Set and default values
across all Scala generators. Included tests to account for new changes.

This also reverts the community contribution to remove ListBuffer
imports and change the default for array to ListBuffer. Users should use
the instantiation types map to modify the desired array instantiation
type. Any new default should target a new minor release after community
discussion, as it affects all existing SDKs generated with
openapi-generator.

* [scala] Improve default handling of monadic collection type

* [scala] Regenerate samples

* Update ScalaPlayFrameworkServerCodegen.java

Scala Play defaulted to List and should continue to do so.
