The profile field is changed by code inside and outside the decoder,

Maintaining it consistency with studio_profile is messy.

The code is also faster with more realistic input though the difference
is small here as that is far from the worst cases the fuzzers pick out

error_resilience: move the MECmpContext initialization into ER code
...
Currently, it needs to be initialized by the ER caller (which is
currently either a mpegvideo decoder or h264dec). However, since none of
those decoders use MECmpContext for anything except ER, it makes more
sense to handle it purely inside ER.
