Purpose

Support Scala 3 enum for Reads/Writes/Format.

Background Context

There is a previous PR #1176.
I think there is another approach about that, more consistent with the existing API/codebase.

• Keep implementation separate from complex macros in JsMacroImpl
• Keep API separate in JsValueMacros as for Value classes
• Inspired by [[https://github.com/lloydmeta/enumeratum/blob/master/enumeratum-reactivemongo-bson/src/main/scala/enumeratum/EnumHandler.scala enumeratum]]
• Inspired by [[https://github.com/ReactiveMongo/ReactiveMongo-BSON/blob/master/api/src/main/scala-3/EnumHelper.scala ReactiveMongo-BSON]]
