Update metadata for MDS3

[aseigler]

• Update JSON metadata statements to support MDS3 format. The way the statements are formatted are true and correct to the best of my knowledge. Should help push along FIDO MDS V3 #565.
• Add transports, algorithms (prioritizing ed25519), and firmware version to ctap_get_info(). Update constants for all attributes in ctap_get_info(). Firmware version is dependent on fido2/version.mk getting updated, which uses git describe. When the firmware gets updated, the metadata should get updated as well in MDS.
• Add authenticatorGetInfo() details to JSON formatted metadata statements. Current getinfo() data should look like approximately like this:

(versions=['U2F_V2', 'FIDO_2_0', 'FIDO_2_1_PRE'], extensions=['credProtect', 'hmac-secret'], aaguid=AAGUID(0076631b-d4a0-427f-5773-0ec71c9e0279), options={'rk': True, 'up': True, 'plat': False, 'credMgmt': True, 'clientPin': False}, max_msg_size=1200, pin_uv_protocols=[1], max_creds_in_list=20, max_cred_id_length=128, transports=['usb', 'nfc'], algorithms=[{'alg': -8, 'type': 'public-key'}, {'alg': -7, 'type': 'public-key'}], firmware_version=262401)
