Rename decoderInputFormat in transformer renderers

- This format is passed to the PassthroughPipeline, which doesn't use
  any decoder.
- In most other cases where it is used, it is not relevant that this
  format will be or has been passed to the decoder. What's relevant is
  that it is the format of the input.
