cpu: Added MTAGE-SC and multi-poTAGE+SC branch predictors
The original papers for both predictors can be found here:
- MTAGE-SC => https://www.jilp.org/cbp2016/paper/AndreSeznecUnlimited.pdf
- multi-poTAGE+SC => https://www.jilp.org/cbp2014/paper/MichaudSeznec.pdf
They are similar and both inherit from a newly created MTAGEBase class
