libavcodec/x265: detect csps in libx265_encode_init_csp()
...
Without this change, if you link with an 8bit libx265 and try to specify
a 10bit input color space via:
ffmpeg -i in.mov -c:v libx265 -pix_fmt yuv420p10le out.mp4
It will error with:
Incompatible pixel format 'yuv420p10le' for codec 'libx265',
auto-selecting format 'yuv420p'
With this fix, it will learn if a 10bit libx265 is available at startup,
and thus allow 10bit input color spaces.
