Identify JSX strings (for js2-mode)

* lisp/progmodes/js.el (js-jsx--syntax-propertize-tag): Derived modes
like js2-mode may use font-lock-syntactic-face-function to apply faces
to JSX strings (and only JSX strings).  Apply the js-jsx-string text
property to such strings so they can be distinctly identified.
(js-jsx--text-properties): Ensure the js-jsx-string text property gets
cleaned up, too.
