Cart line item meta field values not saved when using SerializedCarts

Description

Steps to reproduce:

1. Add a new meta field to an order system meta class.
2. Edit an instance of the meta class in Commerce Manager.
3. Enter a value for your field and save the change.
4. Edit the same instance again.

Expected: The value saved in step 3 should be shown.
Actual: The default value is shown.
Note after resolved: The fix is work for only primitive data types. Since serialized data is save as string in json format in database so we cannot resolve issue for complex types like: File, ImageFile, DictionarySingleValue, EnumSingleValue, DictionaryMultiValue, EnumMultiValue, StringDictionary.
