V6 major changes
1. the way d3dlibs created, adding a load function. Added dlclose in free
function.
2. Simplified the public sync API by only keeping av_d3d12va_wait_idle.
3. Wrapping data->[0], data[1], data[2] into one single structure.

Now we only have scale filter that can be auto inserted. This patch set
basically gives the potential capability to add more auto filters. An auto
