Currently, we use std::chrono to record `command_submit`, `command_start` and `command_end` timestamps for host tasks. So, if there there is a mix of device tasks and host tasks submitted to the queue, they have a different time base and inconvenient to use/compare. This PR makes host task timestamps to have the same time base as device tasks.
