commit: c5e73f8c91dd7a6aa7587b60e526b3e3a915bb3b

summary:
[3.15] gh-153300: Set global configuration variables in PyConfig_Set()
(GH-153301) (#153356)
gh-153300: Set global configuration variables in PyConfig_Set() (GH-153301)
PyConfig_Set() now also set global configuration variables. For
example, PyConfig_Set("inspect", value) now also sets Py_InspectFlag.
Use PyConfig_Set() in main.c to set the inspect flag. Python code can
now see the updated sys.flags.inspect value.
(cherry picked from commit 9fb713f1b8b774c789db007e3824c766a626ccff)
