[New-bugs-announce] [issue39968] move extension modules' macros of `get_xx_state()` to inline function.

[hai shi]

New submission from hai shi <shihai1991 at 126.com>:

as victor and petr said in PR18613：inline function is more better than macros, so I plan move all extension modules' macros of `get_xx_state()` to inline function.

Note: some inline get_xx_state() can not be used directly in `tp_traverse`、`tp_free` and `tp_clear`(issue39824).
