Issue #3214409 by codebymikey: Improve the Editor plugin behaviour supports image styles and uses DOM parser

• Resolve entity references using the editor module. The existing solution always returned true since it was essentially comparing FALSE >= 0.
• Add support for updating references to multiple attributes (src and srcset by default).
• Add support for updating references to image styles.
• Add a revision log explaining why the entity was updated.
• Use interfaces to aid with dependency injection on non-standard installs.
• Also broke down functionality into methods to aid with OOP.

Closes #3214409
