asimd detection on macos 15.3

The library detects `asimd` via
```
info.features.asimd = GetDarwinSysCtlByName("hw.optional.AdvSIMD");
```
However,
```
sysctl -a | grep -i simd                               
hw.optional.arm.AdvSIMD: 1
```
I.e. I suggest to fix this by
```
info.features.asimd = GetDarwinSysCtlByName("hw.optional.AdvSIMD") || GetDarwinSysCtlByName("hw.optional.arm.AdvSIMD");
```
for backward compatibility.
