libcef: Update due to underlying chromium changes.

- WebKit API changes.
- Use full path for the config.h include to ensure that the correct file is loaded.
- Include features_override.gypi as part of the GYP build command.
- Set the 'resource_include_dirs' value in the 'libcef' GYP target in an attempt to avoid RC1102 internal errors when compiling resources on the build bot.
- Change type of BrowserRequestContext 'cache_path' parameter to FilePath.
- Change in base.gyp project targets.
