ENH: cleanup/reorganize surfaceWriter and fileFormats

- remove unused surfaceWriter constructors, noexcept on methods

- relocate/rename writerCaching from surfMesh -> fileFormats

- changed from surfaceWriters::writerCaching to
  ensightOutput::writerCaching to permit reuse elsewhere

- relocate static output helpers to ensightCase

- refactor NAS coordinate writing
