Sanity check |fill_mode| in CFX_AggDeviceDriver.

- In general, FXFILL_ALTERNATE and FXFILL_WINDING should never be set at
  the same time.
- SetClip_PathFill() should not be called for stroke operations.

Add helper functions to do these checks, and also use them to make the
existing code more readable.
