FYI none of these switches are relevant to WebView -- they will only be used by
chrome.  Is there a need to move them?

kSbDisableAutoUpdate is used in safe_browsing_service.cc so need to move it out.
it's possible other switches may not necessarily need moving, however it's good
to have them in one place for component's sake.
