FileSystem: Get rid of VFS::resolve_path().
...
The only remaining client was resolve_symbolic_link() which now deals in
custodies instead.

FileSystem: Port most of the code over to using custodies.
...
The current working directory is now stored as a custody. Likewise for a
process executable file. This unbreaks /proc/PID/fd which has not been
working since we made the filesystem bigger.
This still needs a bunch of work, for instance when renaming or removing
a file somewhere, we have to update the relevant custody links.

FileSystem: Add a Custody class that represents a parent/child guardianship.
...
A custody is kind of a directory entry abstraction that represents a single
entry in a parent directory that tells us the name of a child inode.
The idea here is for path resolution to produce a chain of custody objects.

VFS: Also respect the sticky bit of the new parent in rename().
...
Obviously we should not allow overwriting someone else's files in a sticky
directory either.

VFS: Implement sticky bit behavior for rename() and unlink().
...
Removing entries from a sticky directory is only allowed when you are either
the owner of the entry, or the superuser. :^)

Kernel: Fix rename() sometimes failing to move within the same directory.
...
It was wrong to do a reverse name lookup on the old inode after adding
a new name for it, since we might very well get the new inode instead of
the old one, depending on hash table layouts.

Kernel: Start using StringView in the VFS class.

The less kmalloc() we can do, the better. Calling kmalloc() disables all
interrupts while it runs, so it's directly affecting responsiveness.
