airframe-codec: Scala.js support with Pure Scala packer/unpacker (#789)

* Add InfiniteByteArrayBuffer

* Rename some methods

* Add pure-scala unpacker

* Use ListMap to preserve MapValue element order

* Use pure-Scala packer/unpacker for Scala.js

* Run codec tests for Scala.js too

* Support java collection

* Fix Seq codec

* Reformat

* Do not use pure-Scala msgpack for JVM for safety
