cmake: Don't pass -undefined,error to Apple linker

Browse Source 
Error is the default for this option in ld64, and with the new linker
in Xcode 15 the option was deprecated, causing a warning, so let's just
skip adding it and assume undefined symbols results in errors.

Fixes: QTBUG-116732
Pick-to: 6.6 6.5
