kho: add support for preserving vmalloc allocations
A vmalloc allocation is preserved using binary structure similar to global
KHO memory tracker. It's a linked list of pages where each page is an
array of physical address of pages in vmalloc area.
kho_preserve_vmalloc() hands out the physical address of the head page to
the caller. This address is used as the argument to kho_vmalloc_restore()
to restore the mapping in the vmalloc address space and populate it with
the preserved pages.
