[master] RFR: 8318011: [Lilliput] Fix CDS narrowKlass encoding [v2]

[Roman Kennke]

> With Lilliput, we need to store the correct narrowKlass in the archived Klass instances. For this, we need the ArchiveHeapWriter::precomputed_narrow_klass_shift. However, ArchiveHeapWriter is only available when building with INCLUDE_CDS_JAVA_HEAP, i.e. currently not with Windows. This field should be moved to ArchiveBuilder, so that we can access it even when INCLUDE_CDS_JAVA_HEAP is not enabled.
