Port power measurement script to use selenium
Use selenium so that it's easy to run the script on different browsers
such as Edge. As a result add support for fullscreen video by double
clicking on the video element which works for common sites.

+Newer IPG versions might also require Visual C++ 2010 runtime to be installed:
+ https://www.microsoft.com/en-us/download/details.aspx?id=14632
+
+Install selenium via pip: `pip install selenium`
+
+And finally install the web drivers for Chrome (and Edge if needed):
+ http://chromedriver.chromium.org/downloads
+ https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
+
Sample runs:
python measure_power_win_intel.py --browser=canary --duration=10 --delay=5
--verbose --url="https://www.youtube.com/watch?v=0XdS37Re1XQ"
--extra-browser-args="--no-sandbox --disable-features=UseSurfaceLayerForVideo"
+
+It is recommended to test with optimized builds of Chromium e.g. these GN args:
+
+ is_debug = false
+ is_component_build = false
+ is_official_build = true # optimization similar to official builds
+ use_goma = true
+ enable_nacl = false
+ proprietary_codecs = true
+ ffmpeg_branding = "Chrome"
+
+It might also help to disable unnecessary background services and to unplug the
+power source some time before measuring. See "Computer setup" section here:
