cmd/cue/cmd: make eval use output flags

Mostly for consistency sake.

An Eval Mode is added to filetypes to support this.

Retains the old behavior of eval as much as possible.
Few changes:
- The header is now printed to stderr before
  error messages
- The Encoder now prints headers using `//` for CUE.
  This ensures the output CUE is valid in case only a
  single schema is printed.

Also removes "final" as a tag option.
