build: MSVS warning suppression option tidy-up

Browse Source 
- in `win32/libssh2_config.h` replace `_CRT_SECURE_NO_DEPRECATE` with
  `_CRT_SECURE_NO_WARNINGS`, to use the official macro for this, like
  in CMake.

  Also, it's now safe to move it back under `_MSC_VER`.

  Suppressing:

  `warning C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead.`
  `warning C4996: 'getenv': This function or variable may be unsafe. Consider using _dupenv_s instead.`

- move `_CRT_NONSTDC_NO_DEPRECATE` to `example` and `tests`.
  Not needed for `src`.

  Suppressing:

  `warning C4996: 'strdup': The POSIX name for this item is deprecated. Instead, use the ISO C and C++ conformant name: _strdup.`
  `warning C4996: 'write': The POSIX name for this item is deprecated. Instead, use the ISO C and C++ conformant name: _write.`

- move `_WINSOCK_DEPRECATED_NO_WARNINGS` from source files to
  CMake files, in `example` and `tests`. Also limit this to MSVC.

  Suppressing:

  `warning C4996: 'inet_addr': Use inet_pton() or InetPton() instead`

TODO: try fixing these instead of suppressing.

Closes #929
