gh-152715: Add pythoninfo-build command to Platforms/Apple

[vstinner]

Add a pythoninfo-build command to Platforms/Apple to display build info of the build Python. The command runs "make pythoninfo".

The "ci" and "build" commands now also run "pythoninfo-build".

• Issue: Platforms/Apple: add pythoninfo-build command to display build info of the build Python #152715

[vstinner]

My plan is to backport this change to 3.14 and 3.15 branches, and then modify the buildbot configuration to add a step running the new pythoninfo-build command.

I made similar changes (with buildbot changes) on:

• WASI: gh-151929: Add pythoninfo commands to Platforms/WASI #152136
• Emscripten: gh-151929: Add pythoninfo-build command to Platforms/emscripten #152210

See also pending PR #152713 for Android.

Thanks for the review+merge @freakboy3742!

My plan is to backport this change to 3.14 and 3.15 branches, and then modify the buildbot configuration to add a step running the new pythoninfo-build command.

Oh, the buildbot configuration has a "Configure and compile build Python" step which runs "python3 Platforms/Apple build iOS build" and with this change, the step already runs test.pythoninfo on the build Python:

CC.version: Apple clang version 16.0.0 (clang-1600.0.26.6)
os.cpu_count: 8

os.uname: posix.uname_result(sysname='Darwin', nodename='ip-10-0-98-195.ec2.internal', release='24.6.0', version='Darwin Kernel Version 24.6.0: Wed Nov  5 21:33:59 PST 2025; root:xnu-11417.140.69.705.2~1/RELEASE_ARM64_T8112', machine='arm64')
platform.architecture: 64bit Mach-O
platform.platform: macOS-15.7.3-arm64-arm-64bit-Mach-O

sys.version: 3.16.0a0 (heads/main-dirty:564c58c718b, Jul  1 2026, 05:53:24) [Clang 16.0.0 (clang-1600.0.26.6)]

system.hardware: Mac14,3
system.uptime: 11 days, 8:44:27

I will leave the configuration as it is for now, since pythoninfo is now run as expected. But maybe later the configuration can be modified to run each step (configure, build, pythoninfo) as separated buildbot steps to separate the logs (to make logs easier to read).
