[AOT] Don't set the 'CorrectedSynthesize' flag in the objc_imageinfo section. (#21451)
* [AOT] Don't set the 'CorrectedSynthesize' flag in the objc_imageinfo section.
According to Apple's headers, it's not used anymore, and ignored.
However, with Xcode 13.3, it seems Apple has re-used this value for something
else, and it's causing warnings in the linker:
> ld: warning: '[...]/arm64/Xamarin.iOS.dll.o' was built with class_ro_t pointer signing enabled, but previous .o files were not
Fixes https://github.com/mono/mono/issues/21450.
Ref: https://opensource.apple.com/source/objc4/objc4-818.2/runtime/objc-abi.h.auto.html
* Don't set the 'CorrectedSynthesize' flag when using LLVM either.
