Switch windows CI builds to Github Actions and Qt6 (#2606)

* Make build compatible with ninja generator

* Remove usage of Qt Windows Extras under qt6

* Avoid compilation noise on UNICODE redefinition

* Remove "KviHeapObject::operator new" signature for debug builds, add placement new operator

* Fix implicit cast of 0 to QFlags

* Fix Avoid ambiguous overload in concatenating strings

* KviIpcSentinel::winEvent - Adapt to changed method signature in qt6

* Remove windows 95/98/me support :)

* appveyor: try switching qt version

* Try creating a github action for windows build

* Remove appveyor config; move windows-only patches into dist/windows/patches
