This commit moves the allocation of the resources required for
PrivateInodeVMObject from its constructors to its factory functions.

This commit moves the allocation of the resources required for
InodeVMObject from its constructors to the constructors of its child
classes.
We're making this change to give the child classes the chance to expose
the fallibility of the allocation.
We now use AK::Error and AK::ErrorOr<T> in both kernel and userspace!
This was a slightly tedious refactoring that took a long time, so it's
not unlikely that some bugs crept in.
Nevertheless, it does pass basic functionality testing, and it's just
real nice to finally see the same pattern in all contexts. :^)
This makes for nicer handling of errors compared to checking whether a
RefPtr is null. Additionally, this will give way to return different
types of errors in the future.
