When adjusting metadata_bytes for the residency of the pagemap root, we previously subtracted r.pagemap_bytes (which includes both sizeof(PageMap) and all arena-allocated internal and leaf nodes). This caused all dynamically allocated pagemap metadata to be eliminated from metadata_bytes whenever residency reporting was enabled. PiperOrigin-RevId: 968266034

Fix pagemap root residency adjustment in metadata_bytes.
When adjusting metadata_bytes for the residency of the pagemap root,
we previously subtracted r.pagemap_bytes (which includes both sizeof(PageMap)
and all arena-allocated internal and leaf nodes). This caused all
dynamically allocated pagemap metadata to be eliminated from metadata_bytes
whenever residency reporting was enabled.
