Add migration wizard to assist with migrating bound projects to the new format

[duncanp-sonar]

Description

Moving from the old Connected Mode settings format to the new format means undoing the changes made to the file system and to C# and VB.NET projects during binding. The number of changes required could be considerable so a wizard should be provided to help automate the clean-up.

End-users may have customized how the Connected Mode settings are referenced e.g. by moving settings from project files to a Directory.Build.props file or other imported file. As a result, it is unlikely that the wizard will be able to completely automate the cleanup. In some cases, it will be necessary for end-users to finish the cleanup by manually editing the project files.
