Zhao Zhili ff094f5ebb avutil/channel_layout: make pre-defined channel layouts C++ friendly 
C++ doesn't support designated initializers until C++20. We have
a bunch of pre-defined channel layouts, the gains to make them
usable in C++ exceed the losses.

Bump minor version so C++ project can check before use these defines.

Also initialize .opaque field explicitly to reduce warning in C++.
