qdbuscpp2xml: Register QtDBus metatypes

Browse Source 
Explicitly register QtDBus-specific metatypes before attempting
to generate output. This fixes a bug when types like QDBusObjectPath
are sometimes ignored by this tool. Export QDBusMetaTypeId::init()
for that reason. Add a regression test to tst_qdbuscpp2xml.

Fixes: QTBUG-34550
