The macro guard of #if defined(_WIN32) && !defined(__CYGWIN__) is comes from yohhoy's implementation
and that's not consistence with util/u_uthread.h, this caused it's hard to understand.
Now we change the behavior that's always rely on how meson detecting HAVE_PTHREAD.
So we always disable detecting of threads on Win32 as it's always included in the kernel32 library to
avoid detecting pthreads in mingw.

We already require Windows Vista or later before this commit;
So the code for Windows XP can be removed.

According to c11 standards, there is 4 variant of mtx_init parameter,
mtx_plain
mtx_timed
mtx_plain|mtx_recursive
mtx_timed|mtx_recursive
Directly use mtx_recursive is not a thing, so we need make sure mtx_plain and mtx_plain|mtx_recursive are not equal,
So now we choose the values from Android c11 threads.h for enum mtx_plain, mtx_recursive, mtx_timed, to make sure
c11/threads.h be more c11 conformance, and can raise error when the type parameter of mtx_init are not one of
mtx_plain
mtx_timed
mtx_plain|mtx_recursive
mtx_timed|mtx_recursive

And we support for four types of mtx init enum values that define by C11 standard:
0 mtx_plain - a simple, non-recursive mutex is created.
2 mtx_timed - a non-recursive mutex, that supports timeout, is created.
1 mtx_plain | mtx_recursive - a recursive mutex is created.
3 mtx_timed | mtx_recursive - a recursive mutex, that supports timeout, is created.
musl library also use these enum combination

Now thrd_t are a struct that contains both thread handle and thread id.
For threads that not created by thrd_create, thrd_current are returning pseudo thread handle;
but we can still compare threads differences by using thread id.
