Simplify XFA_DrawImage() and related code

- Remove default arguments, since all callers pass in those parameters.
- Remove a bitmap nullptr check, since all callers do the same check
  already.
- Combine ProgressiveDecoder::GetNumComponents() and GetBPC(), since
  XFA_DrawImage() is the only caller and it wants the combined
  bits-per-pixel value.
- Pass in the bpp value into XFA_GetDIBFormat() and also simplify that.
