cli/command: move PrettyPrint utility to cli/command/formatter

[thaJeztah]

This utility was only used internally, and has no external consumers; move it to the "formatter" package, which is also imported in all files using this utility.

Go SDK: `cli/command`: Move `PrettyPrint` utility to `cli/command/formatter`.
