GetWorkflowHistory payload size exceeds limit for a single page

[drewhoskins-temporal]

Is your feature request related to a problem? Please describe.

A workflow page with large payloads can exceed the GRPC limit.
For example, a user might have a proxy that has a 4MB limit and when downloading a page of history with GetWorkflowHistory that has large payloads in it (such as activity args), it could be larger than that limit.

This gets the workflow into a state that's difficult-to-impossible to recover from.

Describe the solution you'd like

Dunno. Try pagination through smaller pages if there's a size problem? Implement a payload store?
