Pull request description:
This PR is a client-side version of #18453, per review feedback there and [review club discussions](https://bitcoincore.reviews/18453#meeting-log). It updates `bitcoin-cli -getinfo` on the client side to display wallet name and balance for the loaded wallets when more than one is loaded (e.g. you are in "multiwallet mode") and `-rpcwallet=` is not passed; otherwise, behavior is unchanged.

This PR can be manually tested by building, creating/loading/unloading several wallets with `bitcoin-cli createwallet/loadwallet/unloadwallet` and running `bitcoin-cli -getinfo` and `bitcoin-cli -rpcwallet=<wallet-name> -getinfo`.
`wallet_multiwallet.py --usecli` provides regression test coverage on this change, along with `interface_bitcoin_cli.py` where this PR adds test coverage.
