[Qt-creator] Switching to more "semantic" versioning scheme

[Eike Ziller]

We want to switch Qt Creator to semantic versioning, which means bumping the major version for each feature release, since we don’t keep binary compatibility between these.

- Next release after 4.15 is Qt Creator 5.
- Followed by Qt Creator 6 in December 2021.
- Qt Creator 7 in spring 2022
- and so on.

The major version of Qt Creator doesn’t have any meaning at the moment, so we’d like to give it one. We almost always do incremental changes instead of major overhauls in one go, so basing the major version on some kind of feature change doesn’t make much sense. Bumping the major version for each feature release sounds more sensible because of this, and fits the semantic versioning scheme.
