Merge bitcoin/bitcoin#34269: wallet: disallow creating new or restoring to an unnamed (default) wallet

Browse Source 
75b704df9d wallettool: Disallow creating new unnamed wallets (Ava Chow)
5875a9c502 wallet: disallow unnamed wallets in createwallet and restorewallet (Ava Chow)
d30ad4a912 wallet, rpc: Use HandleWalletError in createwallet (Ava Chow)

Pull request description:

  We've been moving in the direction that all wallets must have a name. Therefore, we shouldn't allow creating new unnamed wallets. `createwallet`, `restorewallet`, and the wallet tool's `create` and `createfromdump` all now require the user to provide a non-empty wallet name when creating/restoring a wallet.

  The GUI is already enforcing this, but we were not enforcing it for RPCs or in the underlying `CreateWallet` and `RestoreWallet` functions.

  Wallet migration does still need to be able to restore unnamed wallets, so there is a new argument to `RestoreWallet` to explicitly allow that behavior for migration only.
