accounts/usbwallet: support trezor passphrases (#16503)

Browse Source 
When opening the wallet, ask for passphrase as well as for the PIN
and return the relevant error (PIN/passphrase required). Open must then
be called again with either PIN or passphrase to advance the process.

This also updates the console bridge to support passphrase authentication.
