This commit makes the JSON parser raise an exception when handling objects or arrays whose declaration is incomplete, as in missing the closing marker (brace or bracket) and if the missing marker would have been the last non-whitespace character in the incoming string. Since CPython's JSON parser would raise an exception in such a case, unlike MicroPython's, this commit aligns MicroPython's behaviour with CPython. This commit fixes issue #17141.
