This relands https://dart-review.googlesource.com/c/sdk/+/205633 but without renaming TARGET_OS_IPHONE to DART_TARGET_OS_IPHONE. It also changes uses of TARGET_OS_IOS to DART_TARGET_OS_MACOS_IOS to be consistent with the rest of the VM. TargetConditionals.h for XCode 13 defines several TARGET_OS_* preprocessor symbols that confuse the Dart build. There is probably a more targeted fix for this, but renaming the symbols that Dart uses will also prevent this problem if more symbols are added to the platform headers in the future. See: https://github.com/dart-lang/sdk/issues/46499 TEST=It builds.
