[Cherry-pick for 2.0.1 verified patch]Harden user PII in analytics (#5512) harden analytics (#5604)
* Harden user PII protection logic and extend TrainingAnalytics to expose detailed configuration parameters. (#5512) * Hash128 is not a cryptographic hash, replace with HMAC-SHA256. * Extend TrainingAnalytics side channel to expose configuration details * Change member function scopes and hash demo_paths * Extract tbiEvent hashing method and add test coverage * Fixing the analytics side-channel for curriculum learning. (#5586) * Fixing the analytics side-channel for curriculum learning. * Made a more robust test. * Update the changelog. * Update com.unity.ml-agents/CHANGELOG.md Co-authored-by: Maryam Honari <[email protected]> Co-authored-by: Maryam Honari <[email protected]> * update CHANGELOG Co-authored-by: Jason Bowman <[email protected]>
