Some cleanup of fpdf_render_loadimage.cpp

- Generalise GetBits8()
- Get rid of C-style casts.
- Make CFX_DIBSource::SetDownSampleSize() non const. It's only overriden
  once and called in one place and it doesn't make sense for it to be const.
- Get rid of a macro
- Make public member vars of CPDF_DIBSource private
- And others...
