Function: synchronize_device_with_timeout

Description

Blocks app execution until the compute device has completed all preceding requested tasks. This API is enhanced based on synchronize_device and allows users to set the timeout interval. When an app is abnormal, the app automatically exits based on the configured timeout interval. When the app exits due to timeout, ACL_ERROR_RT_STREAM_SYNC_TIMEOUT is returned.

In the multi-device scenario, the device of the current context is waited.
