Enable pedantic warnings in C++ podspecs (facebook#34404)

Summary: Pull Request resolved: facebook#34404 Mirrors D38457812 (facebook@063c2b4) and D38632454 (facebook@06b55a3), this enables pedantic warnings for iOS in OSS, so that the warning level matches the internal. This is enabled through the `GCC_WARN_PEDANTIC` xcconfig flag (part of "Apple Clang - Warning Policies"), which controls whether "-pedantic" is passed to clang.
