* lisp/progmodes/js.el (js-jsx--put-syntax-table): New function for
consistently ensuring smooth js2-mode integration.  js2-mode sets
syntax-table temporarily while parsing buffers—seemingly to recover
from parsing interruptions—and then it later clears syntax-table
blindly.  When integrating with js-mode, this means that unterminated
string quotes are re-broken in JSX (i.e., they become strings again,
often stringifying large regions of the buffer which should not be
strings).  We try to treat quotes in JSXText as non-strings by setting
syntax-table to a non-“string quote” syntax class, but that stops
working if we lose the property.  On the js2-mode end, by scanning for
this second js-jsx-syntax-table property, we can recover the
syntax-table property there.
(js-jsx--text-range, js-jsx--syntax-propertize-tag): Use
js-jsx--put-syntax-table for above reason.
(js-jsx--text-properties): Clear the js-jsx-syntax-table property too.
