Use separate attribute for callCallbackImmediately to avoid breaking by-ref closure loop

The previous commit reused ImmediatelyInvokedClosureVisitor::ATTRIBUTE_NAME for
callbacks that are invoked immediately (e.g. array_map). This caused a regression
because NodeScopeResolver::processClosureNode uses that same attribute to break
the do-while loop after one iteration (correct for IIFEs called once, but wrong
for array_map callbacks called multiple times with by-ref variables like &$isVariadic).

Introduces a new CALL_CALLBACK_IMMEDIATELY_ATTRIBUTE_NAME constant to distinguish
"callback invoked immediately by a function" from "IIFE called exactly once".
