Make WriteBitmapToPng() handle FPDFBitmap_BGR format.

FPDFViewEmbedderTest includes test cases for all 4 following formats:
FPDFBitmap_Gray, FPDFBitmap_BGR, FPDFBitmap_BGRx, FPDFBitmap_BGRA. But
BitmapSaver::WriteBitmapToPng() is only able to handle 3 of them.

This CL adds the handling for FPDFBitmap_BGR in WriteBitmapToPng() so
that we can compare bitmap results for all possible formats from
FPDFViewEmbedderTest visually.
