Drop [CEReactions] from CharacterData operations to match the DOM specification:
I believe WebKit had this because Attr used to have Text child nodes. Therefore, modifying those Text child nodes via the CharacterData API could modify the value of an attribute, requiring us to run attributeChangedCallback for Custom Elements. However, as of Bug 171688, Attr can no longer have Text child nodes.
I have also verified that Blink does not have [CEReactions] for those methods.
