gh-85283: Add PySys_Audit() to the limited C API
This function was added in Python 3.8 by the PEP 578 "Python Runtime Audit Hooks". It is needed to convert some stdlib extensions to the limited C API, like fcntl, resource and syslog. Move also non-limited "PerfMap" C API from Include/sysmodule.h to Include/cpython/sysmodule.h.
