serial_recovery: Replace CBOR decoding code with generated code
- Add the cddl_gen repository as a submodule.
- Add a CDDL description file for the serial recovery packets to be
decoded.
- Add generated code files and cddl_gen's CBOR library to CMakeList.txt
for Zephyr.
- Convert boot_serial.c to use the new code.
- Add a bash script to (re)generate code files using cddl_gen.py.
Serial recovery should work exactly as before, but the binary should be
about 1k smaller.
