08f3e0873a perf vendor-events: Fix all remaining invalid JSON files 
Remove trailing commas. A later commit will make the parser more strict
and these will not be valid anymore.

d02d5dc882 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

In general the "PublicDescription" fields are not modified when somewhat
significantly worded differently than the standard.

Apart from that, description and names for events slightly different to
standard are changed (to standard) for consistency.

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

a44e4f3ab1 perf vendor events arm64: Fix commas so PMU event files are valid JSON 
No functional change.

Add and remove extra commas in the arm64 JSON files so that the files
can be parsed and validated by other utilities such as Python that fail
to parse invalid JSON.

Committer testing:

d35c595bf0 perf vendor events arm64: Revise core JSON events for eMAG 
Split the PMU events into meaningful functional groups.  Update core pmu
events based on supported ARMv8 recommended IMPLEMENTATION DEFINED
events.

The JSON files are updated with reference to a PMU table shared here:

  https://github.com/AmpereComputing/ampere-centos-kernel/blob/amp-centos-7.5-kernel/Documentation/arm64/eMAG-ARM-CoreImpDefined.pdf

Changes in v3:
- Removed CHAIN event as it wouldn't be useful in Perf - William
- Will factor out events 0x00-0x38 in a follow-on patch - William
- to armv8-recommended.json
Changes in V2:
- Provided documentation for changes - John, William
- Broke up into meaningful groups - William
