[qt5-webengine] Depend on atl instead of atlmfc

[tsondergaard]

qt5-webengine only requires atl, it does not use mfc. Switching to just atl means installations of Visual Studio and Visual Studio Build Tools do not need to explicitly include
Microsoft.VisualStudio.Component.VC.ATLMFC.

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

This matches the documentation at https://doc.qt.io/Qt-5/qtwebengine-platform-notes.html#windows

Thanks!
