windows: use built-in _WIN32 macro to detect Windows 
Windows compilers define `_WIN32` automatically. Windows SDK headers
or build env defines `WIN32`, or we have to take care of it. The
agreement seems to be that `_WIN32` is the preferred practice here.
Make the source code rely on that to detect we're building for Windows.

Public `curl.h` was using `WIN32`, `__WIN32__` and `CURL_WIN32` for
Windows detection, next to the official `_WIN32`. After this patch it
only uses `_WIN32` for this. Also, make it stop defining `CURL_WIN32`.

There is a slight chance these break compatibility with Windows
compilers that fail to define `_WIN32`. I'm not aware of any obsolete
or modern compiler affected, but in case there is one, one possible
solution is to define this macro manually.

grepping for `WIN32` remains useful to discover Windows-specific code.

Also:

- extend `checksrc` to ensure we're not using `WIN32` anymore.

- apply minor formatting here and there.

- delete unnecessary checks for `!MSDOS` when `_WIN32` is present.

** Macros for test source code readability/maintainability.
**
** All of the following macros require that an int data type 'res' variable
** exists in scope where macro is used, and that it has been initialized to
** zero before the macro is used.
**
** exe_* and chk_* macros are helper macros not intended to be used from
** outside of this header file. Arguments 'Y' and 'Z' of these represent
** source code file and line number, while Arguments 'A', 'B', etc, are
** the arguments used to actually call a libcurl function.
**
** All easy_* and multi_* macros call a libcurl function and evaluate if
** the function has succeeded or failed. When the function succeeds 'res'
** variable is not set nor cleared and program continues normal flow. On
** the other hand if function fails 'res' variable is set and a jump to
** label 'test_cleanup' is performed.
**
** Every easy_* and multi_* macros have a res_easy_* and res_multi_* macro
** counterpart that operates in the same way with the exception that no
** jump takes place in case of failure. res_easy_* and res_multi_* macros
** should be immediately followed by checking if 'res' variable has been
** set.
**
** 'res' variable when set will hold a CURLcode, CURLMcode, or any of the
** TEST_ERR_* values defined above. It is advisable to return this value
** as test result.
