[EarlyReturn] Deprecate ChangeOrIfContinueToMultiContinueRector

[TomasVotruba]

Deprecates ChangeOrIfContinueToMultiContinueRector and drops it from the early-return set.

Splitting a single || condition into multiple continue ifs makes the code longer and harder to follow in most cases - the reader has to mentally re-join the conditions that belong together.

The rule did this:

 foreach ($cars as $car) {
-    if ($car->hasWheels() || $car->hasFuel()) {
+    if ($car->hasWheels()) {
+        continue;
+    }
+    if ($car->hasFuel()) {
         continue;
     }

     $car->setWheel($newCar->wheel);
 }

The original single if is the more readable form, so the rule is deprecated instead of kept.
