bcachefs: bcachefs_metadata_version_cached_backpointers

Cached pointers now have backpointers.

This means that we'll be able to kill cached pointers in the
bucket_invalidate path, when invalidating/reusing buckets containing
cached data, instead of leaving them around to be cleaned up by gc_gens
garbago collection - which requires a full metadata scan.
