enum_names: Support naming types with a string

Browse source 
In his ZeekWeek 2022 presentation, @stevesmoot mentioned that he had a
difficult time looking up enum names when all he had was a string
naming the type.

Add support to enum_names() to transparently lookup the type if a string
is provided. This is similar in how record_fields() behaves when being
passed a string.
