Re: [custom-elements-tests] Custom Elements: Element definition (#2940)

Thank you so much, @domenic.
* All reviews fixed (except one, to merge to one test, please see comment)
* Added two more tests as suggested.
* Converting `observedAttributes` needs more study for me, I'll split it to a separate test.
* Took your 2nd suggestion for prototype to rethrow.
