perf arm_spe: Decode event types for new features
Decode new event types introduced by FEAT_SPEv1p4, FEAT_SPE_SME and FEAT_SPE_SME. The printed event names don't strictly follow the naming in the Arm ARM. For example, the "Cache data modified" event is shown as "HITM", and the "Data snooped" event is printed as "SNOOPED". Shorter names are easier to read while preserving core meanings.
