Use the objectid, type, offset natural order as it's more readable and
we're used to read keys like that.

Similar to btrfs_truncate_item(), this is void in the kernel as the
failure case is simply BUG_ON(). Additionally there is no root
parameter as it's not used in the function at all. Make these changes
and update the callers.

This syncs accessors.[ch] from the kernel. For the most part
accessors.h will remain the same, there's just some helpers that need to
be adjusted for eb->data instead of eb->pages. Additionally accessors.c
needed to be completely updated to deal with this as well.
This is a set of files where we will likely only sync the header going
forward, and leave the C file in place as it needs to be specific to
btrfs-progs.
This forced a few "unrelated" changes
- Using btrfs_dir_item_ftype() instead of btrfs_dir_item_type(). This
is due to the encryption changes, and was simpler to just do in this
patch.
- Adjusting some of the print tree code to use the actual helpers and
not the btrfs-progs ones.
A local definition of static_assert is used to avoid compilation
failures on older gcc (< 9) where the 2nd parameter is mandatory.

Now that all callers are using the _nr variations we can simply rename
these helpers to btrfs_item_##member/btrfs_set_item_##member and change
the actual item SETGET funcs to raw_item_##member/set_raw_item_##member
and then change all callers to drop the _nr part.

We have this pattern in a lot of places
item = btrfs_item_nr(slot);
btrfs_item_size(leaf, item);
btrfs_item_offset(leaf, item);
when we could simply use
btrfs_item_size_nr(leaf, slot);
btrfs_item_offset_nr(leaf, slot);
Fix all callers of btrfs_item_size() and btrfs_item_offset() to use the
_nr variation of the helpers.

This function lies in the kernel-shared directory and is supposed to be
close to 1:1 copy with its kernel counterpart, yet it takes one extra
argument - root. But this is now unused to simply remove it.

This function exists in kernel side but using the _item suffix, and
objectid argument is placed before the name argument. Change the
function to reflect the kernel version.
