[Development] MSVC2012 in CI

[Sean Harmer]

Hi,

Can MSVC 2012 configurations be removed from the CI please? My understanding is that this compiler was only kept around to support Windows EC but that this is now removed from 5.7. In particular this compiler is a blocker to using a using declaration such as:

template<typename T>
using QNodeCreatedChangePtr = QSharedPointer<QNodeCreatedChange<T>>;

Kind regards,

Sean
