[MSCTF][SDK] Implement TF_IsCtfmonRunning (#6233)

- Add many global variables.
- Add GetUserSIDString, InitUserSidString,
  InitUniqueString, and
  GetDesktopUniqueName helper functions.
- Implement TF_IsCtfmonRunning function.
- Fix CicFileMapping class in
  <cicero/cicfmap.h>.
- Modify msctf.spec.
- Half-implement ProcessAttach and
  ProcessDetach functions.
