Support rename with SetFileInformationByHandle
Implement SetFileInformationByHandle when class=FileRenameInfo.
Recent clang-cl.exe has started to use SetFileInformationByHandle to
rename a file.
info is FILE_RENAME_INFORMATION. FileName contains the path to rename.
It might be absolute path, or might be relative path from CWD.
