Replace nearly all kRespect with kIgnore

- Encoders and decoders always assume kIgnore.
- They are less opinionated about F16 and color space,
  we just trust the color space that's passed in, and
  put that directly in the image (no sRGB encoding).
- SkBitmap and SkPixmap read/write pixels functions were
  defaulting to kResepct, those are now always kIgnore.
- Many other bits of plumbing are simplified, and I
  added a default of kIgnore to SkImage::makeColorSpace,
  so we can phase out that argument entirely.
- Still need to add defaults to other public APIs that
  take SkTransferFunctionBehavior.

- This makes gold think that we've dramatically changed
  the contents of all F16 images, but that's because
  it doesn't understand the (now linear) color space
  that's embedded. Once we triage them all once, they
  will work fine (and they'll look perfect in the browser).
