feat: Add logging of the contents of the aot cache to the map file

[Delawen]

Adding to the assembly mapfile the assets of the code cache.

Tests in https://github.com/Delawen/jdk/actions/runs/27264662339

The map file is generated for example with -Xlog:aot+map=trace,aot+map+oops=trace,aot=warning:file=${FOLDER}/aot.map:none:filesize=0

Example of output:

For NMethods:
Pointer : @@ Nmethod Size Compilation Level Compilation ID Method signature

Fort the rest:
Pointer : @@ Kind Size ID Name

@vnkozlov Ready to integrate ;)

On a normal execution (-XX:AOTCacheOutput=...) there are two map files generated: one after training and the other at the end describing the final cache. This logs the contents of the aot code cache on the final one, the one that regular developers will want to check.

I haven't been able to properly explore the aot code cache after training and before assembly, maybe it is empty? This intermediate map file would be useful only for Leyden debugging purposes ("why does my method not end up in the cache I use on production if it is stored on the training run?"), so I would just merge this and maybe come back later to try to fill that map file.
