Make message registries use 2 digit versions

Redfish specification, section 9.5.11.2 says:

The MessageId property value shall be in the format:
<MessageRegistryPrefix>.<MajorVersion>.<MinorVersion>.<MessageKey>

bmcweb in certain places has incorrectly used the 3 digit version
instead of the 2 digit version.  This commit fixes that by modifying the
parse_registries script to generate 3 separate struct entries to
represent the registry version, and parse them where appropriate.

MessageRegistryFileCollection uses the 3 digit version.  No behavior
changes.
Message/event log entries use the 2 digit version.  This will cause a
MessageId change from:
Base.1.19.0.InternalError
to
Base.1.19.InternalError

This is a breaking change, so a new option to allow the old behavior is
provided.

Tested: Redfish Service validator passes.
Heartbeat events on EventService show 2 digit versions.
