It is only active for zstd versions 1.4.6 and newer. That means it is disabled currently, but will become active when a later patch in this series updates the zstd library in the kernel to 1.4.6. This header allows the zstd upgrade to 1.4.6 without changing any callers, since they all include zstd through the compatibility wrapper. Later patches in this series transition each caller away from the compatibility wrapper. After all the callers have been transitioned away from the compatibility wrapper, the final patch in this series deletes it.

This is used in decompress_unzstd.c so the internal structure of the library isn't exposed. This allows us to upgrade the zstd library version without modifying any callers. Instead we just need to update decompress_sources.h.
