[Support] Improve flexibility of binary blob formatter.
This makes it possible to indent a binary blob by a certain number of bytes, and also makes some things more idiomatic. Finally, it integrates this binary blob formatter into ScopedPrinter which used to have its own implementation of this algorithm.
