Updated appveyor config:

- Update build image from Visual Studio 2017 to Visual Studio 2019.
 - Updated Qt static library from Qt5.9.7 to Qt5.9.8.
 - Added commands to update vcpkg port files (this does not update already installed packages).
 - Updated vcpkg package list as per #17309.
 - Removed commands setting common project file options. Now done via common.init.vcxproj include.
 - Changed msbuild verbosity from normal to quiet. Normal rights a LOT of logs and impacts appveyor job duration.
Updated msvc project configs:
 - Updated platform toolset from v141 to v142.
 - Updated Qt static library from Qt5.9.7 to Qt5.9.8.
 - Added ignore for linker warning building bitcoin-qt program.
 - Added missing util/str.cpp class file to test_bitcoin project file.
