[libpas] Enable libpas on macOS
https://bugs.webkit.org/show_bug.cgi?id=231815
Reviewed by Saam Barati.
Enabling libpas on x64 macOS. Previously, we enabled it only on AppleSilicon.
This helps stressing libpas on fuzzers more. And it offers large performance
improvement.
1. Speedometer2 is 2.1% improved on low-end macOS (MBA8,2) and 1.7% improved on high-end macOS (MBP14,1).
2. JetStream2 is neutral on both.
