Add crypt_dump_json() API call.

Browse Source 
Add API call that can directly print JSON metadata area from LUKS2 device.

For commandline it also adds --dump-json-metadata option for luksDump action.

Note that the binary metadata (UUID, version etc) is not part of this output.
(We reserve flags parameter to be able to add this later.)
