[FEATURE] Porting NuttX CI Job from Intel Mac to Apple Silicon Mac

[lupyuen]

Is your feature request related to a problem? Please describe.

As suggested by Nathan: We seek help to port our NuttX CI Job from Intel Mac to Apple Silicon Mac (M1, M2, etc).

Today our CI Workflow build.yml (on macOS) calls cibuild.sh:

cd nuttx/tools/ci
./cibuild.sh -i -c -A -R testlist/macos.dat

Which runs OK on Intel Mac. But on Apple Silicon Mac, cibuild.sh calls darwin.sh which:

1. Fails to install gperf and kconfig_frontends. So we comment out the script and install gperf, kconfig_frontends ourselves.

2. Then it fails to install Cython. And we're stuck here:

   + pip3 install 'Cython<3.0'
   error: externally-managed-environment
   × This environment is externally managed
   ╰─> To install Python packages system-wide, try brew install

Describe the solution you'd like

We hope to have cibuild.sh and darwin.sh running successfully on Apple Silicon Macs because:

• Intel Macs are becoming obsolete (Apple still supports them, but doesn't sell them)
• And folks like me can run the NuttX CI Job on Our Own Build Servers
• But we should keep the old CI Job running on Intel Macs, because some folks still use Intel Macs

Describe alternatives you've considered
