libkernel: address: ensure to_pfn can only be called on PA

calculating a PFN from a VA makes no sense since it could be mapped to
any address. Therefore, ensure that it can *only* be called on PAs.

Having the ability to use the `FrameAlloctor`, simulating via the heap

libkernel: CpuOps: add 'static trait bound
...
The CpuOps trait should never hold a reference to any other object. In
fact, it should be a singleton object which is constructed at kernel
boot and live for the entire lifetime of the system. Therefore, it's
safe to add the `'static` trait bound.

fat32: downcase 8.3 filenames
...
Using mtools to prepare the initrd image results in an image that
exclusively uses 8.3 filenames; as per the spec, the 8.3 filenames are
stored uppercase. However, on most UNIX systems, people are used to
dealing with down-case names; therefore convert the strings to
lower-case before passing back to the user.

libkernel: memory: region: remove breaking assert in expand
...
The `expand` function adds bytes size into the region; the check `size
>= self.size` isn't needed since this is an expanding function, not a
resizing one. To emphasise that, rename the function to `expand_by`.
Also include a bunch of unit tests to ensure that expansion by regions
with differing sizes works correctly.
