[RFC,17/20] perf: Add json file for virt machine supported events

Commit Message

Atish Kumar Patra Feb. 17, 2024, 12:57 a.m. UTC

The linux driver will use the event encodings specified in platform
specific json file only for platforms with counter delegation support.

Use the perf json infrastructure to encode those events and let the
driver uses that if counter delegation is available.
