Codec2BufferUtils: use libyuv to copy between NV12 and I420

In previous algorithm copying U/V planes between interleaved format (NV12) and
planar format (I420) is quite not efficient. libyuv provides NV12ToI420 and
I420ToNV12 copy functions which we could utilize if the source and destination
formats are met.

In practice, the consuming time for copying one image could save more than a
half by using libyuv.
