perf: Remove libpython support and legacy Python scripts

Remove embedded Python interpreter support (libpython) from perf, as
all Python scripts have been migrated to standalone scripts using the
perf Python extension module.

Changes include:
- Remove libpython detection and build flags from Makefile.config.
- Remove legacy Python script installation rules from Makefile.perf.
- Delete tools/perf/util/scripting-engines/trace-event-python.c and
  tools/perf/scripts/python/Perf-Trace-Util/Context.c.
- Remove Python scripting engine registration from
  trace-event-scripting.c.
- Remove libpython from the supported features list in builtin-check.c
  and Documentation/perf-check.txt.
- Delete the legacy Python scripts and bin wrappers in
  tools/perf/scripts/python/ and update shell tests.
