useProposalWithOffchainVoteStatus: Allow Array of proposals to be passed

[jtrein]

If we allow the useProposalWithOffchainVoteStatus hook to accept more than a single proposal, we can get status information about many proposals and also use the built-in polling. An example of where we could use this effectively is inside useProposals, or other proposal-listing components.

When using Multicall we can make a single call using and then get the results of each proposal's 3 separate chain calls by grouping using every 3rd array index.

[
  // Proposal 1
  call1,
  call2,
  call3,

  // Proposal 2
  call1,
  call2,
  call3,
]
