With VM_MEM_SRC_ANONYMOUS_HUGETLB, we currently can only use system default hugetlb pages to back the testing guest memory. In order to add flexibility, now list all the known hugetlb backing src types with different page sizes, so that we can specify use of hugetlb pages of the exact granularity that we want. And as all the known hugetlb page sizes are listed, it's appropriate for all architectures.
Besides, the helper get_backing_src_pagesz() is added to get the granularity of different backing src types(anonumous, thp, hugetlb).
