JCA workmanager and bootstrap-context "name" attributes are read-write

The "name" attributes for workmanager and bootstrap-context resources are read-write and should be read-only. They represent the value of the last element of the resource address and thus should not be changed independently of adding/removing the resource.

Where we find these "name" attributes we've been converting their handling such that when they get registered in ManagementResourceRegistration, it is done like this:

mrr.registerReadOnlyAttribute(NAME, ReadResourceNameOperationStepHandler.INSTANCE);

where "NAME" is an AttributeDefinition.

With that, the "add" handler for the resource shouldn't store the name in the model.
