[x265] how to build x265 that supports both 8bit and 10bit

[Mario *LigH* Rohkrämer]

One rather easy solution for Windows users with little compiler 
experience is

https://github.com/jb-alvarado/media-autobuild_suite

which installs an MSYS2 environment and compiles (depending on its 
configuration) ffmpeg with many linked codecs and additionally separate 
encoders; x265 is specifically supported in different configurations, 
including multilib builds.
