WFLY-9288 - Handle EJB session auto creation for stateless locators

[jaikiran]

The commit here implements the semantics noted in https://issues.jboss.org/browse/WFLY-9288. It also includes a test case to verify the change. Going forward, with this commit, the following will happen:

• If the incoming invocation is on a stateful EJB and the invocation is backed by a stateless locator, then a new session gets auto-created and is used for that invocation (and any invocation through the newly converted locator).

NOTE - This above change is a change in semantics from previous versions where the invocation on stateful beans backed by a stateless locator (a.k.a invocations without session) would fail.

• If the incoming invocation is on a stateless EJB and the invocation is backed by a stateful locator, then the invocation is aborted and a failure is returned back to the caller.
