[Qt-creator] Proposal increasing requirement for building Qt Creator 4.7

[Eike Ziller]

https://codereview.qt-project.org/223368
Target branch “master” (will be 4.7)

"Increase requirement for building Qt Creator from Qt 5.6.2 to Qt 5.9

Qt 5.11 will be released and Qt 5.9 is the new LTS.
Increasing the requirement allows us to remove some baggage and
workarounds like Utils::asConst, special Q_OVERRIDE header, and
deployment target adaptions on macOS, and simplifies pulling in
proparser changes from Qt.”

This doesn’t affect the Qt that you use to develop your applications with.

Br, Eike
