doc: Fix qdoc errors for \fn commands in QtConcurrent

This change updates the \fn commands in the QtConcurrent
module, which makes extensive use of templates. Some of the
update \fn commands are very long as a result.

A few cases of the tag trick were used to fix qdoc errors
for some complicated template function signatures that were
marked \internal anyway.
