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

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

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:

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

👍 Makes sense

Thanks for the review+merge @freakboy3742!

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

The new configuration works as expected: a new "Display build info of the build Python" step has been added.
