Fix some bugs in xml.etree.ElementTree.Element's container behavior. (#1816)

Browse Source 
* Have Element inherit from MutableSequence, which is more precise than Sequence.
* Remove unnecessary inherited methods (e.g., __getitem__).
* Correct extend() to take an Iterable. (Sequence was too specific.)
* Alphabetize the typing imports, for sanity.
