Exoplayer: Add support for Landscape mode

To improve reproducibility of tests, it could help to ensure that the
same screen orientation is used on media playback.
This adds a new workload parameter which allows to ensure a LANDSCAPE
mode, which can be useful to better represent video playback scenarios.
When not enforced by the agenda, we enforce a PORTRAIT orientation.
