ci: Add protect against future unguarded API usage

`-Werror=unguarded-availability-new` will protect us from using APIs
that are only available on new macOS / iOS versions without
`__builtin_available` guards.

Fix usage of pthread_jit_write_protect_np() on macOS and iOS

The API is not available on iOS at all, and is only available on macOS
starting from macOS 11, as can be seen in `pthread/pthread.h` in the
Xcode SDK:

```
__API_AVAILABLE(macos(11.0))
__API_UNAVAILABLE(ios, tvos, watchos, driverkit)
void pthread_jit_write_protect_np(int enabled);

__API_AVAILABLE(macos(11.0))
__API_UNAVAILABLE(ios, tvos, watchos, driverkit)
int pthread_jit_write_protect_supported_np(void);
```

The configuration check for this is actually wrong. We should detect
availability of the API at compile time and use it conditionally at
runtime. The code now checks the following cases:

1. Are we building for macOS?
2. Do we have a new-enough SDK that defines MAC_OS_VERSION_11_0 and
   hence has pthread_jit_write_* available?
3. Is the maximum macOS version allowed at least macOS 11.0, so we
   have a possibility of using this API at runtime?
4. Are we running on macOS 11.0 or newer?

Also: we need to ensure that pthread_jit_write_protect_supported_np()
actually returns true before using the API, because if you're shipping
an app, you need to set `com.apple.security.cs.allow-jit` in your app
otherwise the API won't work if you've opted in to Hardened Runtime.
