Oilpan: blink_heap_unittests: Test case have memory leak checked by Lsan

1. For case TraceIfNeeded, modify TraceIfNeededTester to inherit from GarbageCollectedFinalized and at the end of test case TraceIfNeeded trigger a GC.
   After GC, the destructor of TraceIfNeededTester will dereference the RefPtr<OffHeapInt> instance, stop the leak.
2. For case MapWithCustomWeaknessHandling and MapWithCustomWeaknessHandling2, need clear the Persistent handle and trigger a GC at the end of test case.
