device/trezor: webusb transport added, cmake fixes

- webusb transport based on libusb added. Provides direct access to Trezor via USB, no need for Trezor bridge.
- trezor protocol message handler improved, no recursion used. Ready for upcoming integration tests.
- libusb (for docker) bumped from v1.0.9 to v1.0.22, newer version required for webusb transport, for device enumeration.
- cmake improvements and fixes. Cmake Trezor checks are moved to a dedicated CheckTrezor.cmake file. In case of a problem Trezor is excluded from build.
- ifdefs made consistent to Ledger.
- UDP Transport enumeration disabled by default in release mode
