Enum properties generation bug

[chippmann]

Enum property setters in the api are wrongly generated. They try to put themselves into the transfer context rather their enclosing ordinal (id):

  public var mouseFilter: MouseFilter
    get() {
      TransferContext.writeArguments()
      TransferContext.callMethod(rawPtr, ENGINEMETHOD_ENGINECLASS_CONTROL_GET_MOUSE_FILTER, LONG)
      return Control.MouseFilter.values()[(TransferContext.readReturnValue(LONG) as Long).toInt()]
    }
    set(`value`) {
      TransferContext.writeArguments(LONG to value) // <- bug here. should be `value.id`
      TransferContext.callMethod(rawPtr, ENGINEMETHOD_ENGINECLASS_CONTROL_SET_MOUSE_FILTER, NIL)
    }

This leads to:

Exception in thread "main" java.lang.IllegalArgumentException: Failed requirement.

The failing requirement:

    LONG(
        2,
        { buffer: ByteBuffer, _: Int ->
            buffer.long
        },
        { buffer: ByteBuffer, any: Any ->
            require(any is Long) // <- fails here as `any` is not of type `Long` but of type `Enum`
            buffer.variantType = LONG.ordinal
            buffer.putLong(any)
        }
    ),
