[issue17573] add ElementTree XML processing benchmark to benchmark suite

[Antoine Pitrou]

Antoine Pitrou added the comment:

I've committed the benchmarks after some changes:
- smaller document to reduce runtimes
- avoid measuring processing and serializing performance as part of the parsing benchmark
- added an iterparse benchmark (iterparse can be important for e.g. XMPP implementations)
