Improve performance of abort_entries_match (#98932)

* Improve performance of abort_entries_match

In #90406 a ChainMap was added which called __iter__
and __contains__ which ends up creating temp dicts
for matching

174e9da083/Lib/collections/__init__.py (L1022)

We can avoid this by removing the ChainMap since there
are only two mappings to match on.

This also means options no longer obscures data
