nit: Shouldn't this go on the next line?

Done.

fInfo is no longer needed by SkCodec. We can instead call getInfo().

Taking it a step further, we no longer need
getOriginalInfo()
SkCodec::onGetInfo

I thought I would remove the (many) duplicates in subclasses *after* I'm able to
remove the compile-guard (since they are needed in the legacy case).
