Improve build commands for Windows

* Remove surplus backtick
* Add `-DWINDOWS_RESOURCES_ENABLED=OFF`
* Add commands to invoke actual build
* Enable Qt Quick GUI as these commands are mainly meant for development
  where testing the build of the Qt Quick GUI is generally a good idea as
  well

 When building with MSVC, do *not* use any of the MSYS2 shells. The environment of those shells leads to
 build problems. You can however use CMake and Ninja from MSYS2's mingw-w64 packaging (instead of the CMake
 version from Qt's installer). Then you need to specify the Ninja executable manually so the CMake invocation
 would become something like this for UCRT64:
 ```
-`& "$Env:MSYS2_ROOT\ucrt64\bin\cmake.exe" --preset win-x64-msvc-static -DCMAKE_MAKE_PROGRAM="$Env:MSYS2_ROOT\ucrt64\bin\ninja.exe" .

 or for MINGW64:

 ###### Building under Windows for Android
 Building for Android under Windows is still experimental and not regularly tested. It is generally supported
 by CMake, Android tooling and Qt, though. So as long as all dependencies are installed correctly by *some*
