Deprecate PEBS attribute on new platforms

[edwarddavidbaker]

Summary

The goal of this issue is to track changes, discussions, and outstanding issues related to JSON event attributes for Processor Event Based Sampling (PEBS). Specifically PEBS is being replaced with a new attribute Precise in combination with existing attributes such as CollectPEBSRecord.

Replacing the previous PEBS attribute with Precise and CollectPEBSRecord will simplify usage and succinctly describe event capabilities.

Platforms

• All new platforms.
• Existing platforms starting at ICL and ICX.

Overall process

1. Add Precise to above platforms.
2. Update tools and downstream users. Help transition from PEBS to CollectPEBSRecord and Precise.
3. Remove PEBS from the above list of platforms.

Current status

Adding Precise to platforms.
