Fix issues when building more Quiche tests for iOS and Windows

Addresses additional build and test failures for tests run as part of net_unittests in Chromium for iOS and Windows.

Calling WSAStartup in the connect tests avoids the following error in multiple tests on the win-rel bot:
```
ERROR:quic_name_lookup.cc(36)] Failed to look up localhost: Either the application has not called WSAStartup, or WSAStartup failed.
```

Using QUICHE_NO_EXPORT avoids errors like the following on win_chromium_compile_dbg_ng:
```
lld-link: error: undefined symbol: __declspec(dllimport) public: class absl::Status __thiscall quiche::BTreeScheduler<int, int>::Register(int, int const &)
```

The CustomStructWritesTooLittle test changes avoids an unused variable error on ios-simulator.
