RFR: 8358289: [asan] runtime/cds/appcds/aotCode/AOTCodeFlags.java reports heap-buffer-overflow in ArchiveBuilder [v3]

[Vladimir Kozlov]

> There is difference between AdapterFingerPrint allocation size [compute_size](https://github.com/openjdk/jdk/blob/master/src/hotspot/share/runtime/sharedRuntime.cpp#L2227) which may not be aligned to HeapWord size and [size](https://github.com/openjdk/jdk/blob/master/src/hotspot/share/runtime/sharedRuntime.cpp#L2421) used for copying during AOT cache build which is aligned and can be bigger than allocation size. 
> 
> I added asserts to `AdapterFingerPrint` and `AdapterHandlerEntry` to make sure sizes are correct. Both are used in AOT cache build.
> 
> I also moved `FreeHeap()` from `~AdapterFingerPrint()` to enforce the comment and simplify executed code.
> 
> Thanks to @MBaesken for finding the issue and @iklam for pointing the cause.
> 
> Testing tier1-3, xcomp, stress. Higher tiers are still running.
