Removes all resolved uses of convertFromHTMLToContentBlocks_DEPRECATED

Summary:
Removes all uses of `convertFromHTMLToContentBlocks_DEPRECATED` except those that haven't been safely transitioned to `convertFromHTMLToContentBlocks2`, i.e. Recruiting Tools confirmation email template editor and the test case for `convertFromHTMLToContentBlocks_DEPRECATED` itself.

**Note:** this diff will not be landed until a few days after D15844900 is pushed, to ensure all internal customers of Draft.js are on board.
