Replace `_beginthreadex()` C runtime calls with native win32 API `CreateThread()`. The latter was already used in `src/tool_doswin.c` and in UWP and Windows CE builds before this patch. After this patch all Windows flavors use it. To drop PP logic and simplify code. While working on this it turned out that `src/tool_doswin.c` calls `TerminateThread()`, which isn't recommended by the documentation, except for "the most extreme cases". This patch makes no attempt to change that code. Ref:9a2663322c#17572 Ref: https://learn.microsoft.com/windows/win32/api/processthreadsapi/nf-processthreadsapi-terminatethread Also: - use `WaitForSingleObjectEx()` on all desktop Windows. Ref:4be80d5109Ref: https://sourceforge.net/p/curl/feature-requests/82/ Ref: https://learn.microsoft.com/windows/win32/api/synchapi/nf-synchapi-waitforsingleobjectex - tests: drop redundant casts. - lib3207: fix to not rely on thread macros when building without thread support.
