[c/c++] Alias Wmissing-format-attribute to Wsuggest-attribute=format


Since Wsuggest-attribute=[pure|const|noreturn] was introduced, it
makes sense to have Wsuggest-attribute=format. This patch makes this
the canonical form of Wmissing-format-attribute (the old form is still
accepted and documented).

Bootstrapped and regression tested.

OK?
