@matejcik Please

• review introduced protobuf messages (https://github.com/trezor/trezor-firmware/pull/4826/commits/ba06f21a0ea9eccc8088239a6f6105288b86cfcc https://github.com/trezor/trezor-firmware/pull/4826/commits/98c317c34dd0e29a11c4b969383c27e5cb7deee4 https://github.com/trezor/trezor-firmware/pull/4826/commits/cb7ac84d8a1cedd09058f467b4fc41feda80df63)
• review the interface of the introduced trezorlib functions: ethereum.sign_tx_new, ethereum.sign_tx_eip1559_new (https://github.com/trezor/trezor-firmware/pull/4826/commits/9ece9ae6c03881d1af9535915ba1dcebb6b2a4d1), btc.sign_tx (https://github.com/trezor/trezor-firmware/pull/4826/commits/34309b6d09cea2e13f938a820311690565d9e53b), btc.get_ownership_proof_new (https://github.com/trezor/trezor-firmware/pull/4826/commits/c931332b7517207e547a8845f76902f68701b97c).
• decide what to with the aforementioned functions (keep both the old and the new / break compatibility and keep only the new)

@M1nd3r Please review the rest. Take special care to ensure that the anti-exfiltration protocol is implemented correctly in terms of security in terzorlib.
