RFR: 8369037: Identify owning method for MethodData and MethodCounters in AOT map output [v5]

[María Arias de Reyna]

> Part of https://bugs.openjdk.org/browse/JDK-8369037
> Provides part of fixes needed to resolve https://bugs.openjdk.org/browse/JDK-8363440

> The AOT map file lists many objects without any kind of context of what they represent. For example, `MethodCounters` and `MethodData` do not show to what method they belong to. With this patch, now we can at least link the `MethodCounters` and `MethodData` to the `Method` they belong to.
