Kernel: Make FileSystem::initialize() return KResult
...
This forced me to also come up with error codes for a bunch of
situations where we'd previously just panic the kernel.

Kernel: Make Inode::lookup() return a KResultOr<NonnullRefPtr<Inode>>
...
This allows file systems to return arbitrary error codes instead of just
an Inode or not an Inode.

Kernel/DevFS: Remove redundant DevFS& member from DevFSInode
...
All Inode subclasses can get to their FileSystem via Inode::fs().

Kernel: Make FileSystem::root_inode() return a plain Inode&
...
All file system classes are expected to keep their root Inode object
in memory, so this function can safely return an Inode&.

Kernel: Replace "folder" => "directory" everywhere
...
Folders are a GUI concept. File systems have directories.

Kernel: Remove Inode::directory_entry_count()
...
This was only used in one place: VirtualFileSystem::rmdir(), and that
has now been converted to a simple directory traversal.

Kernel: Make Inode::create_child() take the name as a StringView
...
No sense in forcing callers to construct a String. One more small step
towards not using String in the kernel.

Kernel: Change Inode::{read/write}_bytes interface to KResultOr<ssize_t>
...
The error handling in all these cases was still using the old style
negative values to indicate errors. We have a nicer solution for this
now with KResultOr<T>. This change switches the interface and then all
implementers to use the new style.

Kernel: Introduce the DevFS
...
The DevFS along with DevPtsFS give a complete solution for populating
device nodes in /dev. The main purpose of DevFS is to eliminate the
need of device nodes generation when building the system.
Later on, DevFS will assist with exposing disk partition nodes.
