CPU event mappings for AMD Zen processors can vary within the same family. Hence, switch to using the core generation for mapping events. The core generation can be determined by inspecting family and model combinations.

Also update raw_code.cfg with latest event mappings and add an AMD Zen specific formula for computing the raw event code. The formula assumes that the "event" field occupies bits 35:32,7:0 and the "umask" field occupies bits 15:8 as described in the AMD PPRs.
