internal/workflow: add persistence and logging support

Add workflow.Resume, which takes saved state and resumes a workflow.
The host can pass a Listener to capture task states to pass to it. There
is no offical API for modifying the state of the workflow before
resuming, e.g. to implement retries.

Add per-task logging support. Task functions can accept a *TaskContext
instead of a context.Context, which adds a logging interface that's
implemented by the host to do logging however it wants.
