Note that domctl->u.shadow_op.mb is updated with the new size when setting the p2m pool. - For dom0less domUs, the setting of the p2m pool is called before allocating memory during domain creation. Users can specify the p2m pool size by `xen,domain-p2m-mem-mb` dts property. To actually allocate/free pages from the p2m pool, this commit adds two helper functions namely `p2m_alloc_page` and `p2m_free_page` to `struct p2m_domain`. By replacing the `alloc_domheap_page` and `free_domheap_page` with these two helper functions, p2m pages can be added/removed from the list of p2m pool rather than from the heap. Since page from `p2m_alloc_page` is cleaned, take the opportunity to remove the redundant `clean_page` in `p2m_create_table`. This is part of CVE-2022-33747 / XSA-409.
