config: Update Streamline scripts and configs

Updated the stat_config.ini files to reflect new structure.

Moved to a more generic stat naming scheme that can easily handle
multiple CPUs and L2s by letting the script replace pre-defined #
symbols to CPU or L2 ids.

Removed the previous per_switch_cpus sections. Still can be used by
spelling out the stat names if necessary. (Resuming from checkpoints
no longer use switch_cpus. Only fast-forwarding does.)
