These methods need to move to new corresponding methods in ContentHandler. [[ https://gerrit.wikimedia.org/r/c/mediawiki/core/+/705780 | Here's a patch ]] that does the first part of the work for Content::preSaveTransform.
The signature of the ContentHandler method should be:
- ContentHandler::prepareSave( Content, PageRecord, int, int, UserIdentity ) // TODO: discuss if PageRecord is needed or we can just do PageIdentity/Reference
The process:
[] Do the same as in the referenced patch for all the methods.
[] In all extensions where Content overriding classes override the method - override the ContentHandler method instead

[] Replace all callers. Use ContentHandlerFactory to obtain a ContentHandler, not the Content::getContentHandler method
[] Once all callers and overrides in extensions is done, do some hard deprecations.
