855dd8d592 system: use %LOCALAPPDATA% as default datadir on windows (Matthew Zipkin)

Pull request description:

  Closes https://github.com/bitcoin/bitcoin/issues/2391

  This PR changes the default datadir location on Windows from `C:\Users\Username\AppData\Roaming\Bitcoin` to `C:\Users\Username\AppData\Local\Bitcoin`. This change only applies to fresh installs. To preserve backwards compatibility, on startup we check for the existence of `C:\Users\Username\AppData\Roaming\Bitcoin\chainstate` and if it is there, we continue using the "Roaming" directory as the default datadir location.

  [Note that in Windows 11 this change may be moot:](https://learn.microsoft.com/en-us/uwp/api/windows.storage.applicationdata.roamingfolder?view=winrt-22621)

  > Roaming data and settings is no longer supported as of Windows 11. The recommended replacement is [Azure App Service](https://learn.microsoft.com/en-us/azure/app-service/). Azure App Service is widely supported, well documented, reliable, and supports cross-platform/cross-ecosystem scenarios such as iOS, Android and web. Settings stored here no longer roam (as of Windows 11), but the settings store is still available.
