This profile from our new macOS 14.7 CI machines shows that startup spends a bunch of time in the nsNativeThemeCocoa constructor: https://share.firefox.dev/41dL87f
(This profile was gathered in bug 1938328 comment 6, thanks Henrik!)

We should try to remove the NSButtonCell and NSComboBoxCell construction from the startup path, and maybe create them lazily.
