4. bpo-42146: Unify cleanup in subprocess_fork_exec() (GH-22970)

   * bpo-42146: Unify cleanup in subprocess_fork_exec()
   
   Also ignore errors from _enable_gc():
   * They are always suppressed by the current code due to a bug.
   * _enable_gc() is only used if `preexec_fn != None`, which is unsafe.
   * We don't have a good way to handle errors in case we successfully
     created a child process.

8. bpo-42208: Add _Py_GetLocaleEncoding() (GH-23050)

   _io.TextIOWrapper no longer calls getpreferredencoding(False) of
   _bootlocale to get the locale encoding, but calls
   _Py_GetLocaleEncoding() instead.
   
   Add config_get_fs_encoding() sub-function. Reorganize also
   config_get_locale_encoding() code.

7. bpo-42208: Pass tstate to _PyGC_CollectNoFail() (GH-23038)

   Move private _PyGC_CollectNoFail() to the internal C API.
   
   Remove the private _PyGC_CollectIfEnabled() which was just an alias
   to the public PyGC_Collect() function since Python 3.8.
   
   Rename functions:
   
   * collect() => gc_collect_main()
   * collect_with_callback() => gc_collect_with_callback()
   * collect_generations() => gc_collect_generations()
