8369418: Identify owning class for KlassTrainingData in AOT map output

[Delawen]

Contains patches for: https://bugs.openjdk.org/browse/JDK-8363440
Fixes: https://bugs.openjdk.org/browse/JDK-8369418

Right now, the AOT Map displays the KlassTrainingData like this:

0x00000008002aa5e0: @@ KlassTrainingData 40 0x00000008002ac260: @@ KlassTrainingData 40 

which doesn't provide any context on what class is this training for.

Modify the AOT Map Logger so we can link the class to its training data:

Some of the KlassTrainingData will not reflect a class name because of https://mail.openjdk.org/pipermail/leyden-dev/2025-October/002764.html

I header files, if a type can be forward declared, we usually do not include the its header. In this case, we can use:

class KlassTrainingData;

instead.
