feat(ocpp): add spec-required DisplayMessageCtrlr variables

Add DisplayMessages, SupportedFormats, SupportedPriorities to
OCPP20VariableRegistry per OCPP 2.0.1 spec §3.1.8. Use
OCPP20MessageFormatEnumType for SupportedFormats enumeration.
Connector.ConnectorType deferred (requires isComponentValid
design change per OpenSpec process).
