[X86][llvm-exegesis] fix LNLP performance counter binding issue (llvm#146348)

mahesh-attarde · mattarde · web-flow · commit 84e82746c3ff · 2025-07-01T10:29:23.000+05:30
We added LNLP sched model recently, PFM counter bounding names needs to
match cpu string.
llvm-exegesis wont produce results without correct naming.
