perf vendor events arm64: Reference common and uarch events for Ampere eMag
Reduce duplication in the JSONs by referencing standard events from
armv8-common-and-microarch.json

Apart from that, description and names for events slightly different to

Note that names for events 0x34 and 0x35 are non-standard and remain
unchanged. Those events came from the following originally:
