Allow configuring the EJB subsystem for disabling pass by value semantics for invocations on remote interfaces of beans

The EJB3 spec mandates that the params passed to beans during invocation on a remote interface of the bean, be treated with pass-by-value semantics. Currently we do allow individual applications to override this semantic by setting a per application level configuration which then uses pass-by-reference semantics for in-VM calls on the remote interfaces of the bean. The current setting is allowed in a jboss-ejb-client.xml of the application as follows:

<jboss-ejb-client xmlns="urn:jboss:ejb-client:1.0">
    <client-context>
        <ejb-receivers local-receiver-pass-by-value="false"/>
    </client-context>
</jboss-ejb-client>

We should allow configuring this semantic at the EJB3 subsystem level so that it can be applicable to all EJB applications (unless overridden by the application) deployed on the server.
