 Provide `getWithUserData` and `putWithUserData`

 Summary:
 This makes it possible to serialise Names and FastStrings in user
 programs, for example, when writing a source plugin.

 When writing my first source plugin, I wanted to serialise names but it
 wasn't possible easily without exporting additional constructors. This
 interface is sufficient and abstracts nicely over the symbol table and
 dictionary.
