stdlib: Add a prebuilt MESI_Three_Level cache

Browse Source 
The cache is modeled after an AMD EPYC cache, but not exactly
like AMD EPYC cache.
- K cores per core complex (CCD), each core has one private split L1,
and one private L2.
- K cores in the same CCD share 1 slice of L3 cache, which is not
a victim cache.
- There can be multiple CCDs, which communicate with each other via
Cross-CCD router. The Cross-CCD rounter is also connected to
directory controllers and dma controllers.
- All links latency are set to 1.
