Kernel: Make all syscall functions return KResultOr<T>
...
This makes it a lot easier to return errors since we no longer have to
worry about negating EFOO errors and can just return them flat.

Kernel: Make sys$anon_create() fail if size == 0
...
An empty anonymous file is useless since it cannot be resized anyway,
so let's not support creating it.

Kernel: Add anonymous files, created with sys$anon_create()
...
This patch adds a new AnonymousFile class which is a File backed by
an AnonymousVMObject that can only be mmap'ed and nothing else, really.
I'm hoping that this can become a replacement for shbufs. :^)
