[WFLY-2764] Cleanup messaging operation descriptions

Clean up all messaging resources that were building their descriptions
manually instead of relying on AttributeDefinition &
OperationDefinition.

Sort keys in LocalDescriptions.properties in lexicographic order and
remove unused keys

There is no change to the messaging subsystem management model or the
XML schema.
The messaging parser refactoring is an internal clean up where the
transport parameters were put into the transport :add operation. Now they
are in their own :add operation and simply use the TransportParamDefinition add
handler (that was already existing).
