wm4 5f2a8474ae video: uninline memcpy_pic functions 
There's literally no reason why these functions have to be inline (they
might be performance critical, but then the function call overhead isn't
going to matter at all).

Uninline them and move them to mp_image.c. Drop the header file and fix
all uses of it.
