perf script: Move script_spec code to trace-event-scripting.c

Browse Source 
The script_spec code is referenced in util/trace-event-scripting but
the list was in builtin-script, accessed via a function that required
a stub function in python.c. Move all the logic to
trace-event-scripting, with lookup and foreach functions exposed for
builtin-script's benefit.
