Cleanup transform usage

Use tint::transform::DataMap for inputs as well as outputs.

This allows tint to nest transforms inside each other (e.g. embedding
transforms inside sanitizers), and still having a consistent way to pass
data in and out of these transforms, regardless of nesting depth.

Transforms can also now be fully pre-built and used multiple times as
there is no state held by the transform itself.

Bug: tint:389
