cr50_fuzz: Add fuzzer for u2f commandsstabilize-ambassador-14268.43.B-cr50_stabstabilize-14268.67.B-cr50_stabstabilize-14268.52.B-cr50_stabstabilize-14268.51.B-cr50_stabrelease-R96-14268.B-cr50_stab
Currently there's only one fuzzer for Pinweaver and one for host
commands in cr50. Add a fuzzer for the u2f commands (generate, sign,
attest) used in the WebAuthn flow to ensure its security. Most regions
of the concerning functions are covered except for pure error code
returns and unreachable regions (currently auth secret is not used in
sign and attest command yet).
Rename old cr50_fuzz namings to pinweaver_fuzz, since they only cover
Pinweaver commands.
