This patch builds upon:
https://lore.kernel.org/lkml/20241015000158.871828-1-irogers@google.com/
as those patches remove a util to test dependency assumed to be
present for "perf build: Remove test library from python shared
object."

The patch:
 - removes workarounds for Python 2 module support due to long
   deprecation and challenges in developing new code;
 - constifies variables and parameters to functions;
 - removes python.c stub code which existed due to missing functions
   that are defined in the builtin-* files, in general the builtin-*
   code is moved into util;
 - remove bench and test perf C code from the python module;
 - adds parse_events to the python perf module.

v3. Move is_directory_at to patch 6 rather than patch 7, respond to
    review feedback on the list from Namhyung.
v2. Add the bottom 4 bullet points - 13 more patches.
