RFR: 8362566: Use -Xlog:aot+map to print contents of existing AOT cache

[Ioi Lam]

Implement `-Xlog:aot+map` in the production run:


$ java -cp HelloWorld.jar -XX:AOTCache=HelloWorld.aot \
    -Xlog:aot+map=file=aot.map:none:filesize=0 \
    HelloWorld


I moved the old logging code from archiveBuilder.cpp into a new fille, aotMapLogger.cpp. I did the following to print the map in the production run:

1. When dumping the AOT cache, `ArchiveBuilder` maintains a list of all the metaspace objects in the archive. However, there's no such list when we are loading from the AOT cache. Therefore, I added a new `RuntimeGatherArchivedMetaspaceObjs` class to discover all the metaspace objects that are stored in the AOT cache.
2. A significant rewrite is needed for printing the oops (see comments around `FakeOop`) because we only have an image of the oops in the AOT cache and these aren't real heap objects.
