Add failing tests for JSX indentation bugs

* test/manual/indent/js-jsx.js: Add failing tests for all the js-mode
and js2-mode JSX indentation bugs reported over the years that I could
find.  Some may be duplicates, so I have grouped similar reports
together, for now; we’ll see for certain which distinct cases we need
once we start actually implementing fixes.
* test/manual/indent/js-jsx-quote.js: New file with a nasty test.
