Motivation
For most uses of permissionless rounds (#3162), applications need to have access to the round number.
Proposal
Expose the round in which the block is being validated to the contract.
This should only be used in multi-leader rounds. The client cannot yet handle all cases where this oracle is consulted in single-leader rounds. (See #3172.)
Test Plan
An example application using this will be added in a separate PR.
