Replace Profile* in declarative_api with BrowserContext*

This will remove the dependence of these files on
chrome/browser/profiles/profile.h, in preparation for their move to extensions/browser/api/declarative.

The tests aren't all fixed yet, but here is the new-look CL.

[Fady Samuel, 2014-09-03 17:28:01]

looks good so far.

After some examination, I think we'll have to forgo the removal of
TestingProfile from rules_registry_service_unittest.cc and from
rules_registry_with_cache_unittest.cc until after these files move. It looks
like then we'll derive these tests from ApiUnitTest to get the
MockExtensionSystemFactory that avoids the need to link to the Chrome (or
possibly just create our own class that includes MockExtensionSystemFactory).
