D801: Freestyle: remove old and unused stroke shaders

This patch removes several stroke shaders written in C++ that are unused
and don't serve a real purpose any more.  The removed shaders are:

  - BPy_ColorVariationPatternShader
  - BPy_StrokeTextureShader
  - BPy_TextureAssignerShader
  - BPy_ThicknessVariationPatternShader
  - BPy_fstreamShader
  - BPy_streamShader

and a few more that weren't even exposed to the Python API.

Some minor edits were made by the reviewer.
