Description

参考 #61030 ，让XPU下面也能使用memory stat相关功能。

示例代码：

import paddle
from paddle.base import core
from paddle import framework

current_device = framework._current_expected_place_()
device_id = current_device.get_device_id()
current_memory_allocated = core.device_memory_stat_current_value("Allocated", device_id)
print(current_memory_allocated)
a = paddle.ones((1024, 1024))
current_memory_allocated_new = core.device_memory_stat_current_value("Allocated", device_id)
print(current_memory_allocated_new)

示例输出：

这里打出来的占用量是4194304，是1024*1024*4byte，符合预期。
