Reason for revert:
Speculative revert for breaking quite a few browser_tests and content_browsertests across multiple platforms:
https://build.chromium.org/p/chromium.webkit/builders/Mac10.6%20Tests/builds/26427
http://build.chromium.org/p/chromium.webkit/builders/Mac10.8%20Tests/builds/9662
http://build.chromium.org/p/chromium.webkit/builders/Win7%20Tests/builds/5566


Original issue's description:
> Move the user agent styles sheets to blink_resources.grd (Part 3)
> 
> Blink should make use of blink_resources.grd for the inline resources of user agent stylesheets.
> This removes the dependency upon using make-file-arrays.py which embeds these resources as strings. 
> 
> Also the .rodata section of libblink_web (in component build mode) is reduced by ~33kb.
