[webkit.UncountedLambdaCapturesChecker] Ignore lambda invocation with arguments (llvm#117394)

Fixed a bug that UncountedLambdaCapturesChecker would emit a warning on
a lambda capture when the lambda is invoked with arguments.
LocalVisitor::VisitCallExpr was not tolerating a lambda invocation with
more than 1 arguments.
