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

## Messages rebuild
Install `protoc` for your distribution.
Install `protoc` for your distribution. Requirements:
- `protobuf-compiler`
- `libprotobuf-dev`
- `libprotoc-dev`
- `python-protobuf`
- `python`
Python 3 is required. If you don't have python 3 quite an easy way is
to use [pyenv].
It is also advised to create own python virtual environment so dependencies
are installed in this project-related virtual environment.
Soft requirement: Python 3, can be easily installed with [pyenv].
```bash
python -m venv /
```
### Python 2
Make sure your python has `protobuf` package installed
Workaround if there is no Python3 available:
```bash
pip install protobuf
pip install backports.tempfile
```
Regenerate messages:
### Regenerate messages
```
./venv/bin/python3 src/device_trezor/trezor/tools/build_protob.py
```bash
cd src/device_trezor/trezor
python tools/build_protob.py
```
The messages regeneration is done also automatically via cmake.
