Remove some unused friend declarations

...which no longer find the befriended classes anyway (and would need to e.g. be
rewritten using non-elabortated type names if they were still relevant) after
f853ec317f6af1b8c65cc5bd758371689c75118d "Extend loplugin:external to warn about
classes" moved the befriending classes into (unnamed) sub-namespaces.  (Except
on Windows, but where clang-cl now flagged them with "error: unqualified friend
declaration referring to type outside of the nearest enclosing namespace is a
Microsoft extension; add a nested name specifier
[-Werror,-Wmicrosoft-unqualified-friend]".)
