David Hildenbrand (Arm) 99573ef4ac mm/pagewalk: drop FW_MIGRATION
We removed the last user of FW_MIGRATION in commit 912aa82595 ("Revert
"mm/ksm: convert break_ksm() from walk_page_range_vma() to folio_walk"").

So let's remove FW_MIGRATION and assign FW_ZEROPAGE bit 0.  Including
leafops.h is no longer required.

While at it, convert "expose_page" to "zeropage", as zeropages are now the
only remaining use case for not exposing a page.
