docs: Internal method for triggering a VM save state with a specified reason
          code. The reason code can be interpreted by device/drivers and thus it
          might behave slightly differently than a normal VM save state.
          
          This call is fully synchronous, and the caller is expected to have set
          the machine state appropriately (and has to set the follow-up machine
          state if this call failed).
          
          
          :py:func:`IMachine.save_state` 
  
          in reason of type :class:`Reason`
              Specify the best matching reason code please.
  
          in progress of type :class:`IProgress`
              Progress object to track the operation completion.
  
          in snapshot of type :class:`ISnapshot`
              Snapshot object for which this save state operation is executed.
  
          in state_file_path of type str
              File path the VM process must save the execution state to.
  
          in pause_vm of type bool
              The VM should be paused before saving state. It is automatically
              unpaused on error in the "vanilla save state" case.
  
          return left_paused of type bool
              Returns if the VM was left in paused state, which is necessary
              in many situations (snapshots, teleportation).
  
          raises :class:`VBoxErrorInvalidVmState`
              Virtual machine state is not one of the expected values.
          
          raises :class:`VBoxErrorFileError`
              Failed to create directory for saved state file.
