windows: simplify detecting and using system headers
- autotools, cmake: assume that if we detect Windows, `windows.h`,
  `winsock2.h` and `ws2tcpip.h` do exist.
- lib: fix 3 outlier `#if` conditions to use `USE_WINSOCK` instead of
  looking for `winsock2.h`.
- autotools: merge 3 Windows check methods into one.
- move Watt-32 and lwIP socket support to `setup-win32.h` from
  `config-win32.h`. It opens up using these with all build tools. Also
  merge logic with Windows Sockets.
- fix to assume Windows sockets with the mingw32ce toolchain.
  Follow-up to: 2748c64d60
- cmake: delete unused variable `signature_call_conv` since
  eb33ccd533.
- autotools: simplify `CURL_CHECK_WIN32_LARGEFILE` detection.
- examples/externalsocket: fix header order.
- cmake/OtherTests.cmake: delete Windows-specific `_source_epilogue`
  that wasn't used anymore.
- cmake/OtherTests.cmake: set `WIN32_LEAN_AND_MEAN` for test
  `SIZEOF_STRUCT_SOCKADDR_STORAGE`.

After this patch curl universally uses `_WIN32` to guard
Windows-specific logic. It guards Windows Sockets-specific logic with
`USE_WINSOCK` (this might need further work).
