The jaxrs subsystem had new attributes added without a schema bump

WFLY-12298 introduced attributes to the jaxrs subsystem. While the schema was bumped, the model version was not. Because of this there is no reliable way to correctly use transformers from WildFly 19 -> WildFly 11. Note that WildFly 11 was the first version to bump to model version 2.0.0 and WildFly 19 kept the same model version, but added the attributes.

JBoss EAP should not be impacted as no releases contain, with the exception of JBoss EAP CD19 and JBoss EAP CD20 Tech Preview releases, the attributes.

We should set the transformers up to reject the attributes for model version 2.0.0 and 1.0.0. An unsupported system property should be introduced to allow the rejection of attributes for 2.0.0 on WildFly mixed domain environments. While this is an unlikely scenario it would be nice to have.
