Implement truncation of RAID stripe-tree entries and add selftests for these
two edge cases of deletion to the RAID stripe-tree selftests.

Changes to v4:
- Use btrfs_set_item_key_save() instead of duplicate item (Filipe)
- Add forgotten btrfs_put_bioc() in selftests (Filipe)

Link to v4:
https://lore.kernel.org/linux-btrfs/20241017090411.25336-1-jth@kernel.org

Changes to v3:
- Use btrfs_duplicate_item() (Filipe)
- User key.offset = 0 in btrfs_search_slot() so we can find "front" delete

Changes to v2:
- Correctly adjust the btree keys and insert new items instead (Filipe)
- Add selftests
