Add a new GetInstance() method for singleton classes, take 2.

This is a small step towards making all singleton classes use the Singleton<T> pattern within their code and not expect the callers to know about it.

This CL includes all files except those under chrome/browser, chrome/net, chrome/service and third_party/WebKit (these will be done in future CLs).

Suggested files to focus for reviewers:
- joi@ for files under src/ceee
- tommi@ for files under src/chrome_frame
- maruel@ for the rest of the files.

BUG=65298
TEST=all existing tests should continue to pass.
