As part of the conversions to replace pgtable constructor/destructors with ptdesc equivalents, convert various page table functions to use ptdescs. Some of the functions use the *get*page*() helper functions. Convert these to use pagetable_alloc() and ptdesc_address() instead to help standardize page tables further.
