GH-91079: Rename C_RECURSION_LIMIT to Py_C_RECURSION_LIMIT ( #108507 )
...
Symbols of the C API should be prefixed by "Py_" to avoid conflict
with existing names in 3rd party C extensions on "#include <Python.h>".
test.pythoninfo now logs Py_C_RECURSION_LIMIT constant and other
_testcapi and _testinternalcapi constants.
