Allow plugins to hook into Find/Replace functionality

[engram-design]

Related to verbb/super-table#114, can other fields hook into Find & Replace functionality? We'd like to be able to copy what Matrix does with Super Table, but all functionality related to that seems to be hardcoded https://github.com/craftcms/cms/blob/develop/src/queue/jobs/FindAndReplace.php#L58.

I imagine this would be useful for other plugins that have their own content tables.

Would love this as well!

Same here!
Have a lot of content inside super-tables and it would be awesome if that could hook into the S&R functionality without doing it manually ourselves.
