Add metrics for tlb and cache statistics:
- finite_cpi: Cycles per Instructions from Finite cache/memory
- est_cpi: Estimated Instruction Complexity CPI infinite Level 1
- scpl1m: Estimated Sourcing Cycles per Level 1 Miss
- tlb_percent: Estimated TLB CPU percentage of Total CPU
- tlb_miss: Estimated Cycles per TLB Miss

For details about the formulas see this documentation:
https://www.ibm.com/support/pages/system/files/inline-files/CPU%20MF%20Formulas%20including%20z16%20-%20May%202022_1.pdf

Output after:
# ./perf stat -M tlb_miss -- dd if=/dev/zero of=/dev/null bs=1M count=10K
... dd output removed
