shmem: Alloc shared memory on a specified memory node

ascend inclusion
category: Feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4NDAW


CVE: NA

-------------------

In some scenarios, there are memory only numa nodes used for designed
process groups. Users need to specify memory nodes to apply for shared
memory.

Here we extend shmem_alloc_and_acct_page() to accept an extra node_id
and supply that node_id through share_pool interface in later patches.
