This opens up the proposer to only optionally create blocks. Nodes may
only make blocks when there are transactions or the chain is scheduled.

title: "proposer: return optional block"
doc:
- audience: Node Dev
description: |
The `ProposerInterface` trait now returns an optional `Proposal`, allowing
for no block to be created. This is a breaking change that only impacts custom
`ProposerInterface` implementations. The change allows more flexibility in choosing
when to create blocks.
