Remove hermes/inspector/chrome/ConnectionDemux.cpp override

Problem Description

To provide a temporary fix for 9662, I'm adding TEMP_UntilReactCommonUpdate/hermes/inspector/chrome/ConnectionDemux.cpp. The corresponding upstream PR is 34342.

This issue is meant to track the removal of the override depending on the upstream acceptance of the change.

Check upstream PR 34342 and issue 9662 first. The temporary override is at TEMP_UntilReactCommonUpdate/hermes/inspector/chrome/ConnectionDemux.cpp; once the upstream change is available, remove that override and verify the behavior described by issue 9662.
