Provide persistence_1_0.xsd and orm_1_0.xsd in $JBOSS_HOME/docs/schema

When building the EAR file using ANT it is useful to validate the various XML files. For an EJB module based on EJB3 there are 2 new XML files: META-INF/persistence.xml and META-INF/orm.xml. Both must conform with these 2 xml schema files:

• persistence_1_0.xsd
• orm_1_0.xsd

Therefore it would be helpful to have both xsd files in $JBOSS_HOME/docs/schema like ejb-jar_3_0.xsd
