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.

v2. Add the bottom 4 bullet points - 13 more patches.
