[CTFMON][SDK] Add ctfmon.exe (#6149)

ctfmon.exe will be a replacement of our
kbswitch.exe in the future. That is the
front-end of Language Bar. It is needed
to support TIPs.
- Add ctfmon.exe at base/applications/ctfmon.
- Add <cicero/cicbase.h>,
  <cicero/CModulePath.h>, and
  <cicero/osinfo.h> headers and use them.
