It was added in the hardened_runtime.xcent that is used for LibreOffice distribution for macOS outside the App Store already last year.
Note that it is plausible that the mention of the extension manager in the comment in hardened_runtime.xcent is a red herring, and that it is just a coincidence that some extension manager code that runs early when LibreOffice is starting is the first code to make use of the dynamic machine code generation in the C++/UNO bridge.
