[lldb-mi] Remove use of dialog box

Summary: This really is only implemented on Windows, and it requires us to pull in User32. This was only useful when debugging on lldb-mi on Windows, and there doesn't seem to be a good reason why using a dialog box is better than what exists for other platforms.
