`make pyprof` runs super slow on `macos-15` GA runner

[yungyuc]

PR #634 temporarily turns off make pyprof step in build_macos-15_Release because one or more profiling scripts takes super long time, like hours:

Run make pyprof
  make pyprof

@KHLee529 suggested:

From the error message it seems like that profile_take_along_axis.py is the script that cause infinite run. Could you please try to first remove this script by renaming it to any name without prefix profile_?

We need to fix the bad profiling script (or SIMD code).

The workflow appears to stuck at the line profile_take_along_axis_simd(test_sa, idx_sa). Switching to macos-15-intel resolves the issue, so I suspect the SIMD code may not be working correctly on arm64. I’ll try to pinpoint the issue, but unfortunately I don’t have access to a Mac myself.

The SIMD code is only with Neon and should be running on arm. It is not executed on x86. Please discuss with @KHLee529 .
