Client command for normalizing a whole Michelson stack

Context

This work has been extracted from my old MR on adding support for TZT. In TZT unit tests, the client has to compare the actual result of the interpreter with the provided expected output; it does so modulo unparsing mode by normalizing both actual and expected results.

Normalization of stacks is probably a useful tool on its own and it is much simpler to implement than full TZT support hence the extraction of this part.
