This PR adds code for setting the Quality of Service (QoS) level of the process on Windows. This can, e.g., make sure that on hybrid systems P-cores are utilized even when the app window is out of focus. In the following cases, it is adjusted from the default behavior: - In wm_jobs.cc the QoS level is raised while a priority job is running. - The command line option `--qos [high|eco|default]` can be used to change the QoS level of the process. - By default, the QoS level is raised for the EEVEE performance tests, as they check viewport rendering performance and would otherwise be reliant on never going out of focus to not get a downgraded QoS level. By default, they are created with an out of focus window at the time of landing this PR. This PR makes sure that they actually measure the animation replay performance attainable during real-world use. Pull Request: https://projects.blender.org/blender/blender/pulls/144224
