This PR ports more of the implementation of availability checking from clang-rt into the Engine. In particular, when the call to look up the symbol `_availability_version_check` fails, this PR falls back on reading the platform version information out of a plist file at a well-known location, as is done [here](https://github.com/llvm/llvm-project/blob/2fd66e6eb659701b9d4c88708d55d5854a246815/compiler-rt/lib/builtins/os_version_check.c#L163). This change fixes a mistake in flutter#44711, which didn't account for `_availability_version_check` not being available on iOS 11 and 12. Fixes flutter/flutter#138711
