Andreas Kling f35108fc31 Kernel: Simplify PageDirectory allocation failure ...

This patch gets rid of the "valid" bit in PageDirectory since it was
only used to communicate an allocation failure during construction.

We now do all the work in the static factory functions instead of in the
constructor, which allows us to simply return nullptr instead of an
"invalid" PageDirectory.
