[compiler-rt][AArch64][FMV] Use the hw.optional.arm.caps fast path (#95275)
MacOS 15.0 and iOS 18.0 added a new sysctl to fetch a bitvector of all
the hw.optional.arm.FEAT_*'s in one go. Using this has a perf advantage
over doing multiple round-trips to the kernel and back, but since it's
not present in older oses, we still need the slow fallback.
