This reverts commit 58d47fa1ec.
Reason for revert: Tree broken
Original change's description:
> Renamed SkSL "offset" to "line"
>
> https://skia-review.googlesource.com/c/skia/+/451419 changed the meaning
> of "offset" throughout SkSL, so that it was actually tracking line
> numbers rather than offsets (and thus had a misleading name). This
> completes the transition by renaming all of the now-misnamed "offset"
> fields, parameters, and variables to "line'.
