Title: Add multi_field support for Mapper externalValue (plugins)

In context of mapper attachment and other mapper plugins, when dealing with multi fields, sub fields never get the `externalValue` although it was set.

Related to https://github.com/elasticsearch/elasticsearch-mapper-attachments/issues/57

Closes #5402.
