selftests/mm: add new test cases to the migration test

Added three new test cases to the migration tests:

1. Shared anon THP migration test
This test will mmap shared anon memory, madvise it to
MADV_HUGEPAGE, then do migration entry testing. One thread
will move pages back and forth between nodes whilst other
threads try and access them.

2. Private anon hugetlb migration test
This test will mmap private anon hugetlb memory and then
do the migration entry testing.

3. Shared anon hugetlb migration test
This test will mmap shared anon hugetlb memory and then
do the migration entry testing.
