Clement Courbet eee2e06e2a [llvm-exegesis][NFC] Add a way to declare the default counter binding for unbound CPUs for a target. 
Summary:
This simplifies the code and moves everything to tablegen for consistency. This
also prepares the ground for adding issue counters.

Clement Courbet 41c8af3924 [MCSched] Bind PFM Counters to the CPUs instead of the SchedModel. 
Summary:
The pfm counters are now in the ExegesisTarget rather than the
MCSchedModel (PR39165).

This also compresses the pfm counter tables (PR37068).
