Doc: Remove unofficial Qt Concurrent headers

<QtConcurrentRun>, <QtConcurrentMap>, and <QtConcurrentFilter> are not
official headers. Developers should use <QtConcurrent> instead.

As a side-effect, this patch also stops the function documentation from
being duplicated (one copy in the QtConcurrent namespace page, one copy
in the \headerfile pages)

(For some reason, \brief doesn't work on standalone pages like these)
