Using an escape sequence, e.g. printf '\e]50;CursorShape=1\a', to change
the cursor shape property like we handle DECSCUSR, i.e. as a transient
change without creating a new profile (see
SessionManager::sessionProfileCommandReceived()).

To test:
- printf '\e]50;CursorShape=1\a' to change the cursor shape, check that the
  current profile hasn't been switched to a new profile (that has no name
  as it's a temp profile)
