Refactor the PrefixSuffixTransformer into separate prefix- and suffix transformers (#4318)

* Refactor prefix filter into its own filter, decoupled from the prefixsuffix filter * Refactor prefix transformer into its own transformer, decoupled from the prefixsuffix transformer * Refactor suffix filter into its own filter, decoupled from the prefixsuffix filter * Refactor suffix transformer into its own transformer, decoupled from the prefixsuffix transformer * Add a default nameSuffix field spec in addition to the namePrefix * Remove the PrefixSuffixTransformer from the list of builtin transformers * Add a multi-transformer to builtinhelpers.TransformFactories * Remove the implementation of the prefixsuffixtransformer.PrefixSuffixTransformer * Resolve style and format related feedback from the pull request * Add test to test the legacy PrefixSuffixTransformer for BC purposes
