Currently the memcg's status is also accounted into the socket's
memory pressure to alleviate the memcg's memstall. But there are
still cases that can be improved. Please check the patches for
detailed info.

v3:
  - Fixed some coding style issues pointed out by Simon
  - Fold dependency into memcg pressure func to improve readability

v2:
  - Splited into several patches and modified commit log for
    better readability.
  - Make memcg's pressure consideration function-wide in
    __sk_mem_raise_allocated().

v1: https://lore.kernel.org/lkml/20230506085903.96133-1-wuyun.abel@bytedance.com/
v2: https://lore.kernel.org/lkml/20230522070122.6727-1-wuyun.abel@bytedance.com/
