The MM subsystem is trying to shrink struct page. This patchset
introduces a memory descriptor for page table tracking - struct ptdesc.
This patchset introduces ptdesc, splits ptdesc from struct page, and
converts many callers of page table constructor/destructors to use ptdescs.
Ptdesc is a foun
Currently, page table information is stored within struct page. As part
of simplifying struct page, create struct ptdesc for page table
information.

No folio equivalents for page type operations have been defined, so
define them for later folio conversions.
Also changes the Page##uname macros to take in const struct page* since
we only read the memory here.

Introduce utility functions setting the foundation for ptdescs. These
will also assist in the splitting out of ptdesc from struct page.
Functions that focus on the descriptor are prefixed with ptdesc_* while
functions that focus on the pagetable are prefixed with pagetable_*.
pagetable_alloc() i
Converts internal pmd_pgtable_page() callers to use pmd_ptdesc(). This
removes some direct accesses to struct page, working towards splitting
out struct ptdesc from struct page.

In order to split struct ptdesc from struct page, convert various
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.
