When trying to reland Node 22 in #44597, we discovered that thin LTO was the root cause of several symbols being stripped from the release build only on MacOS. This does not seem to be an existing problem in either Chromium or upstream Node.

While we debug this, we do want to land Node 22 in main, and root out any bugs well before an alpha/beta branch point. This issue is to reland thin LTO on Mac before Electron 35's stable release.
