Upstream CEF v49 prebuilt binaries and libraries

With these upstream CEF prebuilt binaries and libraries you can build CEF Python from sources in less than 10 minutes. See the Build instructions document for details.

Prebult binaries and libraries were created according to build instructions with the automate.py script by running the automate.py --prebuilt-cef command.

Notes:

• The cefclient and cefsimple sample applications require Vista or later. It should be possible to build these to support XP as well, but it would require modifications to CEF's cmake/ninja configuration in the cef_binary archives. If there are still issues on XP then see upstream Issue #1787.
• The cef_binary archives contain only Release mode binaries
• CEF binaries for v49 (branch 2623) are not available anymore in upstream CEF (neither cefbuilds nor Spotify), as this is an old unsuported branch
