refactor(tvix/castore/fs): remove From<Node> for InodeData r/7931

These were copying unnecessarily. Instead, have a
InodeData::from_node(), which *consumes* the Node entirely, returns
`InodeData` and the split-off name (which is not part of InodeData).

Callers can then use the result in various helper functions, like:

 - InodeData::as_fuse_type
 - InodeData::as_fuse_file_attr
 - InodeData::as_fuse_entry

… to prepare their replies to the kernel.

This removes not only a bunch of clones, but also a lot of copy-pasted
code.
