Remove unreachable code in cgdi_plus_ext.cpp

The only caller to CGdiplusExt::StretchDIBits() always passes in a
bitmap with an alpha channel. Add a CHECK() for that, and then remove
all the code that tried to handle other bitmap formats. Also:

- Remove a redundant GdipDeleteGraphics call.
- Remove support code for calling GdipSetImagePalette(), now that there
  are no callers.
