gh-152711: Add pythoninfo-build command to Platforms/Android

[vstinner]

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

• Issue: Platforms/Android: add pythoninfo-build command to display build info of the build Python #152711

[vstinner]

My plan is to backport this change to 3.13, 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

I prepared PR python/buildmaster-config#748 for the buildbot configuration.
