When you tell x264 "--colormatrix YCgCo", all it does set the VUI flag. It otherwise completely ignores it.
That means that if you send x264 supposed "YUV" data that is in fact YCgCo, it will pass it through unmolested, compress it appropriately, and set the VUI flag for YCgCo.
How you do that depends on your workflow. This plugin will allow it with 8 bit, and will work if x264 reads the script directly or you use something like avs2pipemod.
For 10 bit, I don't personally know much about how high bitdepth inside avisynth works. What I did for a few test clips is have my script output the original BGR, and then use a simple command line application of my own creation to do BGR 8 8 8->YCgCo 10 10 10. Seemed to work fine (but was affected by the madvr "teal bug" at the time).
