Standardise deprecations in CMS 4 for kitchen-sink

[emteknetnz]

recipe/kitchen-sink version of https://github.com/silverstripe/silverstripe-framework/issues/10500

Do the following for all non-silverstripe/installer modules contained in silverstripe/recipe-kitchen-sink

Acceptance criteria

• [ ] Code with a @deprecated annotation throw a Deprecation::notice()
• [ ] Code throwing a Deprecation::notice() is annotated with a @deprecated
• [ ] Standardize the @deprecated annotation

Implementation lessons from 10500

• Use http://github.com/emteknetnz/silverstripe-deprecator
• This will highlight deprecation messages that need to be manually changed - docblock has precedence over Deprecation::notice()
• Undo code-writing commit, manually update messages, commit, then do 2nd commit containing code-writing
