gh-97669: Remove outdated example scripts (#97675)

Remove outdated example scripts of the Tools/scripts/ directory. A
copy can be found in the old-demos project:
https://github.com/gvanrossum/old-demos

Removed scripts (39):

* byext.py
* byteyears.py
* cleanfuture.py
* copytime.py
* crlf.py
* db2pickle.py
* dutree.doc
* dutree.py
* find-uname.py
* find_recursionlimit.py
* finddiv.py
* findlinksto.py
* findnocoding.py
* fixcid.py
* fixdiv.py
* fixheader.py
* fixnotice.py
* fixps.py
* get-remote-certificate.py
* google.py
* highlight.py
* ifdef.py
* import_diagnostics.py
* lfcr.py
* linktree.py
* lll.py
* mailerdaemon.py
* make_ctype.py
* mkreal.py
* objgraph.py
* pdeps.py
* pickle2db.py
* pindent.py
* pysource.py
* reindent-rst.py
* rgrep.py
* suff.py
* texi2html.py
* which.py

Changes:

* Remove test_fixcid, test_lll, test_pdeps and test_pindent
  of test.test_tools.
* Remove get-remote-certificate.py changelog entry, since the script
  was removed.

Note: there is a copy of crlf.py in Lib/test/test_lib2to3/data/.

-"""Find the maximum recursion limit that prevents interpreter termination.
-
-This script finds the maximum safe recursion limit on a particular
-platform.  If you need to change the recursion limit on your system,
-this script will tell you a safe upper bound.  To use the new limit,
-call sys.setrecursionlimit().
-
-This module implements several ways to create infinite recursion in
-Python.  Different implementations end up pushing different numbers of
-C stack frames, depending on how many calls through Python's abstract
-C API occur.
-
-After each round of tests, it prints a message:
-"Limit of NNNN is fine".
-
-The highest printed value of "NNNN" is therefore the highest potentially
-safe limit for your system (which depends on the OS, architecture, but also
-the compilation flags). Please note that it is practically impossible to
-test all possible recursion paths in the interpreter, so the results of
-this test should not be trusted blindly -- although they give a good hint
-of which values are reasonable.
-
-NOTE: When the C stack space allocated by your system is exceeded due
-to excessive recursion, exact behaviour depends on the platform, although
-the interpreter will always fail in a likely brutal way: either a
-segmentation fault, a MemoryError, or just a silent abort.
-
-NB: A program that does not use __methods__ can set a higher limit.
