util: Streamline .apc project convertsion script

This Python script generates an ARM DS-5 Streamline .apc project based
on gem5 run. To successfully convert, the gem5 runs needs to be run
with the context-switch-based stats dump option enabled (The guest
kernel also needs to be patched to allow gem5 interrogate its task
information.) See help for more information.
