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.

The '--' prevented arguments from being passed to the script, such as:

Add stackcollapse.py script as an example of parsing call chains, and
also of using optparse to access command line options.
The flame graph tools include a set of scripts that parse output from
various tools (including "perf script"), remove the offsets in the
function and collapse each stack to a single line. The website also
says "perf report could have a report style [...] that output folded
stacks directly, obviating the need for stackcollapse-perf.pl", so here
it is.
This script is a Python rewrite of stackcollapse-perf.pl, using the perf
scripting interface to access the perf data directly from Python.
