[Bug] Write local activity marker failure data properly

[Sushisource]

Right now Core accepts some Failure proto from lang when a local activity fails, and just writes it into the marker without caring much. In principle, it should likely actually be wrapped in an ActivityFailureInfo and make use of RetryState in order to be deterministically stable in the face of changes to the RetryPolicy for local activities.

@Spikhalskiy If you end up fixing some of this in Java, would appreciate a link to those PRs dropped in here.
