gh-116946: add `Py_TPFLAGS_IMMUTABLETYPE` to several internal types (#138582)

The following types are now immutable:

* `_curses_panel.panel`,
* `[posix,nt].ScandirIterator`, `[posix,nt].DirEntry` (exposed in `os.py`),
* `_remote_debugging.RemoteUnwinder`,
* `_tkinter.Tcl_Obj`, `_tkinter.tkapp`, `_tkinter.tktimertoken`,
* `zlib.Compress`, and `zlib.Decompress`.
