Make appdelegate-objc compilable again on Monterey

where the Xcode version is 14.2 and the SDK version is MacOSX13.1,
by specifically excluding llappdelegate-objc.mm from being compiled using
the C++20 standard. In this case, the standard is reverted to C++17 but
specifically only for that file.

The errors didn't happen on newer SDK versions such as the one in Sonoma
or Sequoia, and the errors looked completely unrelatable:
