avcodec/error_resilience: Only keep what is needed from MECmpContext
ERContext currently has an embedded MECmpContext, despite only
needing exactly one function from it. This is wasteful because
MECmpContext is pretty large (135 pointers, 1080 B for eight byte
pointers). So keep only what is needed.
