This doesn't seem to be needed, forward declare content::WebContents if that's
even needed (already done in the header)

Done.

Updated this comment to mention how it fits into builds.

The difference is:

c/b/ui/browser_dialogs_mac.cc: Only on Cocoa builds.
c/b/ui/views/browser_dialogs_views.cc: Only on non-Mac and mac_views_browser=1.
c/b/ui/views/browser_dialogs_views_mac.cc: On Cocoa builds, and needs to access
Views implementations.

Another aspect behind the difference is that ShowWebsiteSettings is called via a
vtable on BrowserWindow. So, for WebsiteSettings, *all* platforms have the same
definition of the global function to show the dialog, in browser_commands.cc (
https://code.google.com/p/chromium/codesearch#chromium/src/chrome/browser/ui/...
)

We looked into doing the same pattern (i.e. replacing the ShowWebsiteSettings
global function with per-platform definitions). On Mac, both this global
function, and the BrowserWindow member function just end up forwarding
arguments, so it looked promising. However, for Views, some extra arguments from
BrowserWindow private members are added by the member function, so it wasn't a
neat fit.
