[libpas] Enable libpas on ARM64 Darwin platforms (ARM64E is already enabled)
https://bugs.webkit.org/show_bug.cgi?id=234416
Reviewed by Filip Pizlo.
r287168 fixed libpas compare_and_swap on ARM64 so that we pass all libpas tests on ARM64 platforms.
Speedometer2 and JetStream2 are neutral, PLUM3 is 10.79% better, and RAMification is 2.83% better.
