Minor fixes to C++ style guide.

Link to GN style guide fixed.

Added a link to the general C++ style guide from the C++11-specific page.

Text on both the C++ and C++11 pages updated to remove a reference to the wiki (presumably it's referrring to "this page") and instead say to make a CL when there is concensus.
