[Feature Request] General task failure not reporting as LANG_FAIL in replayer

[cretz]

Describe the solution you'd like

When a workflow is run that throws to cause a task failure (not a non-deterministic one though), when that history is run under replayer, the cache remove job has reason LANG_REQUESTED with "Always evict workflows after replay" as if it succeeded. The cache remove job reason is used to determine replay failure or not. Should probably be LANG_FAIL. Should also consider providing the activation failure on the remove job to help lang out.

Note, this is technically a backwards-incompatible behavior change because workflow histories with task failures will start failing in Core-based SDKs. Lang should have release notes saying as much.
