Mitchell Hashimoto dac134d254 pkg/apple-sdk: enable libc++ availability annotations ...

#13417

The bundled upstream libc++ headers in Zig 0.16 skip the Apple-configured
availability setting. This causes the headers to assume every LLVM 21
ABI symbol is present in the target system libc++, producing binaries
that fail at launch on macOS versions without `std::__hash_memory`.

Enable the Apple vendor availability table for compile steps configured
by the Apple SDK helper. libc++ now selects its inline compatibility
implementation when the target system dylib does not provide the symbol.
