CPU/GPU usage comparison with native backends for QMediaPlayer and QMediaRecorder

We should create a table with CPU/GPU/Memory usage upon playing high dpi + high fps videos and upon recording.

The comparison should be made for Windows (D3D rendering, OpenGL rendering), Linux (VAAPI, CUDA hw accelerations), macOS (metal), and Android.

The issue is to be split into tasks.

The comparison should be done after this optimization is done:

Also, it nice to find a cross-platform tool for measurement avg CPU/GPU/RAM.

Note, there's some discussion about performance measurement:
