Fixes #6157

<f:event listener>, <f:ajax listener>, actionListener and valueChangeListener accept a method taking the event or a method taking no arguments. Mojarra creates a MethodExpression per variant and falls back to the other one on MethodNotFoundException.

Composite component listeners. ContextualCompositeMethodExpression.invoke() looks for the method expression of an outer composite component when its delegate throws MethodNotFoundException. When that lookup failed with PropertyNotFoundException, it threw that one, so the caller never fell back to the other variant. A composite actionListener or valueChangeListener with a bean method without arguments failed with HTTP 500. A composite <f:event> or <f:ajax> listener with a method-signature taking the event got null as event on GlassFish, and failed on Tomcat. The lookup is now extracted into invokeOuterCompositeMethodExpression(), which throws the original MethodNotFoundException when the outer expression does not resolve or is no method expression. Any other exception of the lookup or of the invoked outer method still propagates.

valueChangeListener in an include or tag file. EditableValueHolderRule now creates the variant without arguments through the tag attribute, as ActionSourceRule does, and passes both variants to MethodExpressionValueChangeListener(MethodExpression, MethodExpression). The one-argument constructor created that variant without the variable mapper of the Facelet context, so a method without arguments of a bean from ui:param or a tag file attribute failed with "Target Unreachable".

Order. <f:event> and <f:ajax> now try the variant taking the event first, on each invocation, as MethodExpressionActionListener.processAction() specifies. ListenerMethodInvoker does this for both tags.

Behavior change. For <f:event> and <f:ajax>, a bean which has both m() and m(event) now gets m(event), as actionListener and valueChangeListener already do, and as MyFaces does for <f:event>. The same holds for a method taking varargs, which now gets the event. In Development stage, Mojarra logs JSF1113 once per listener for a bean with both methods. The specification does not define this case yet, see jakartaee/faces#2274.

Tests: ListenerMethodInvokerTest, DeserializedListenerTest, ContextualCompositeMethodExpressionTest, and Issue6157IT with 37 cases, green on GlassFish. The IT covers every row of the table in jakartaee/faces#2274, and these listener syntaxes on all four attributes: #{b.m()}, #{b.m(component)}, #{b.m('x')}, #{b['m']}, a method taking a supertype of the event, Object or varargs, a method returning a value, a bean from ui:param, a tag file attribute or a composite component attribute, a method call given to a composite component method attribute, c:forEach, ui:repeat and h:dataTable with the var as argument, f:actionListener and f:valueChangeListener with binding="#{b.m()}", and ui:repeat over beans of different classes. Against the 4.0 branch, 11 of them fail.
