Update msvc and appveyor builds to use Qt5.12.11 binaries (!22224) · Merge requests · bitcoin / bitcoin

Placeholder Aaron Clauson requested to merge github/fork/sipsorcery/msvc_qt5.12.11 into master Jun 11, 2021

Synchronises the Qt version used in the msvc and Appveyor builds with #22054.

I needed to use switch to the Visual Studio 2019 Preview Appveyor image because the compiler version on the non-preview image is too far behind and I had difficulty building a compatible Qt version for it. Once the main Appveyor Visual Studio 2019 image reaches version 16.10.1 it can be used.
