libcef on Windows reduces the Windows Timer resolution to it's minimum (1 millisecond), unnecessarily reducing battery life. #1529

What steps will reproduce the problem?
1. Start an application that uses libcef.dll (TweetDeck Version 3.9.408-3418ce2 
(3.3.7.0-win) for example)
2. Open an administrator prompt and write (powercfg -energy duration 5)
3. Open the generated energy-report.html and notice where it warns that 
TweetDeck has reduced the maximum windows timer resolution and request a 
resolution of 1 ms. You can see in the information section that the timer 
resolution request is attributed to libcef.dll.

What is the expected output? What do you see instead?
I don't expect the timer resolution to be lowered unless some multimedia or 
animations are taking place that require the resolution to be lowered. 
Unnecessarily reducing the timer resolution impacts battery life.

What version of the product are you using? On what operating system?
Using TweetDeck Version 3.9.408-3418ce2 (3.3.7.0-win) on Windows 8.1

This is an issue in Chromium that has already been filed as 
https://crbug.com/411592. CEF will get the fix once that issue has been 
resolved in Chromium.
