(experimental) Compile Cython code with binding=True

[jdemeyer]

When using the Cython compiler directive binding=True, Cython uses a custom type to implement functions and methods. This custom type supports more Python features. The most important changes lie in inspect support.

We find several Cython bugs regarding binding=True:

• ​https://github.com/cython/cython/issues/1658 (not an issue for Sage)
• ​https://github.com/cython/cython/pull/1724 (see #23155)
• ​https://github.com/cython/cython/pull/1728 (see #23155)
