We don't need to inject this in OSS yet, let me know if you think I should remove it.

I can specify a more descriptive name for this map, such as "archetypeAttributesContext." Let me know if you have other suggestions or prefer to keep it generic.

What changed?
Adds metadata context support to history service gRPC calls while setting information before finalizing any mutable state transaction.
Why?
We want to pass mutable state metadata, such as workflow type, activity type, workflow task queue, and activity task queue, throughout the gRPC call lifecycle.
How did you test it?
Note
Introduces a per-request metadata context and populates it with workflow info during state transitions.
