构造一个 synchronized_pool_resource.

1-4) 用指定的上游 memory_resource 构造一个 synchronized_pool_resource 并根据指定的选项调节。结果对象保有 upstream 的副本但不占有 upstream 所指向的资源。
不将 opts 接收为参数的重载以默认构造的 pool_options 实例为选项。不将 upstream 作为参数接收的重载以 std::pmr::get_default_resource() 的返回值为上游 memory_resource 。

5) 复制构造函数被删除。

参数

opts	-	含有构造函数选项的 std::pmr::pool_options 结构体
upstream	-	所用的上游 memory_resource

异常

1-4) 仅若对上游资源的 allocate() 函数调用抛出异常才抛出。是否或在何种条件下发生这种调用是未指定的。
