`intrin.h` defines `_ReturnAddress` for x86 and x86-64, but not ARM64

Basically, I believe that this should compile:
```cpp
#include
void x() {
_ReturnAddress();
}
```

Currently, it compiles for x86 and [AMD64](https://c.godbolt.org/z/vjTv18zW1), but not [x86-64](https://c.godbolt.org/z/MzvTnYKfv).

Microsoft lists it under [ARM64 intrinsics](https://learn.microsoft.com/en-us/cpp/intrinsics/arm64-intrinsics?view=msvc-170).
