yinshengkai f44a31c337 procfs: add memory pressure notification support
This is a memory monitoring interface implemented with reference to Linux's PSI (Pressure Stall Information),
which can send notifications when the system's remaining memory is below the threshold.

The following example code sets two different thresholds.
When the system memory is below 10MB, a notification is triggered.
When the system memory is below 20 MB, a notification (POLLPRI event) is triggered every 1s.

```
int main(int argc, FAR char *argv[])
{
  struct pollfd fds[2];
  int ret;

  if (argc == 2)
    {
      char *ptr = malloc(1024*1024*atoi(argv[1]));
      printf("Allocating %d MB\n", atoi(argv[1]));
      ptr[0] = 0;
      return 0;
    }

  fds[0].fd = open("/proc/pressure/memory", O_RDWR);
  fds[1].fd = open("/proc/pressure/memory", O_RDWR);
  fds[0].events = POLLPRI;
  fds[1].events = POLLPRI;

  dprintf(fds[0].fd, "%llu -1", 1024LLU*1024 * 10);
  dprintf(fds[1].fd, "%llu 1000000", 1024LLU*1024 * 20);

  while (1)
    {
      ret = poll(fds, 2, -1);
      if (ret > 0)
        {
          printf("Memory pressure: POLLPRI, %d\n", ret);
        }
    }

  return 0;
}
```

Summary:
  In the x86 environment, memory does not necessarily start at 0, so when end is 0x0, start = end + 1, and then determine the contents of start, it will cause x86 to cause a crash when accessing an illegal address.
This problem does not occur in the arm environment because arm starts at 0x0, so the content of the 0x1 address is “\0”.
