Welcome: Fix the order of Qt versions for examples

Browse Source 
There are two sources for examples: Qt versions directly, and "example
sets", which are just a tuple of display name, documentation path,
examples path.

The Qt installer registers an "example set" for Qt versions, so to avoid
duplicate entries we match Qt versions to example sets, if found. This
destroys any order the Qt versions might have been in before.

Order the results by Qt version (and other sets last) by first creating
all the items regardless of origin (noting their Qt version in the user
data), and sorting them before adding to the model.

Also use constants for the different user data fields.

Fixes: QTCREATORBUG-31108
