Windows: Compiling FFMPEG 4.3.1 with only LIBVPX and a few filters

My goal was to compile minimal FFMPEG binary on Windows with the following properties:

• is statically-linked
• has jpeg decoder
• has vp8 encoder
• has a few enabled filters
• both win32 and win64

Here's my log as of September 3, 2020.
