fido_assert_allow_cred, fido_assert_empty_allow_list — manage allow lists in a FIDO2 assertion

The fido_assert_allow_cred() function adds ptr to the list of credentials allowed in assert, where ptr points to a credential ID of len bytes. A copy of ptr is made, and no references to the passed pointer are kept. If fido_assert_allow_cred() fails, the existing list of allowed credentials is preserved. For the format of a FIDO2 credential ID, please refer to the Web Authentication (webauthn) standard. The fido_assert_empty_allow_list() function empties the list of credentials allowed in assert.
