Important rework of hw-app-btc

To prepare support of incoming taproot in Bitcoin network, we have a complete rework of hw-app-btc (thanks @kallerosenbaum ). The code shipped is only activated on a future BTC app release and is going to be tested on the next days (you may expect newer version of hw-app-btc if necessary). That said, a user coming with a regular 1.x BTC app will still use the previous code, so it should be non breaking.
