Kernel: Consolidate API for creating AnonymousVMObject with given pages

Browse source 
We don't need to have a dedicated API for creating a VMObject with a
single page, the multi-page API option works in all cases.

Also make the API take a Span<NonnullRefPtr<PhysicalPage>> instead of
a NonnullRefPtrVector<PhysicalPage>.
