Pull request description:

  Adds `contrib/signet/miner` for mining signet blocks.

  Adds `bitcoin-util` cli utility, with the idea being it can provide bitcoin related functionality that does not rely on the ability to access a running node. Only subcommand currently is "grind" which takes a hex-encoded header and grinds its nonce until its nBits is satisfied.

  Updates `getblocktemplate` to include `signet_challenge` field, and makes `getblocktemplate` require the signet rule when invoked on the signet change. Removes connectivity and IBD checks from `getblocktemplate` when applied to a test chain (regtest, testnet, signet).
