[28.x backport] cli/command/*: deprecate formatting-related functions and types

[thaJeztah]

backport:

• depends on / stacked on [28.x backport] cli/command/plugin: fix linting issues, and assorted cleanups #6340
• backport cli/command/container: deprecate NewDiffFormat, DiffFormatWrite #6187
• backport cli/command/*: deprecate formatting-related functions and types #6336
