btrfs-progs: dump-tree: add untyped item ptr helper and use it
There's lots of code that passes btrfs_item_ptr. Add a helper to extract
the ptr at the beginning, ignoring the type. The print functions take
the correct type, but we ignore it in the conversion macros as it does
not provide the type checking anyway.
If the typed variable is used more than once, it's kept in place.

btrfs-progs: introduce key type for persistent permanent items
The number of distinct key types is not that big that we could waste one
for something new we want to store in the tree.
Similar to the temporary items, we'll introduce a new name for an
existing key value and use the objectid for further extension. The
victim is the BTRFS_DEV_STATS_KEY (248).
The device stats are an example of a permanent item.
