remove m_event_context from `Algorithm`
This is meant as a quick fix for the non-reentrant copy of the eventcontext in Algorithm, in case !703 (merged) takes longer..
If this could be tested within the ATLAS codebase now, we could remove the m_eventcontext
completely, also in the LegacyAlgorithmAdapter
in !703 (merged).
built on top of !781 (merged)
