  mythfilldatabase: reduce memory usage.

Mythfilldatabase uses QDomDocument to parse and store the XML data that is read; according to QDomDocument documentation this object is not meant to handle large XML files; QXmlStreamReader should be used in these situations.

This commit replaces QDomDocument by QXmlStreamreader.

A test showed that memory usage dropped from 5.6 GB to 698 MB.

Fixes #13517
