windows: tidy up includes, macros, document dependencies
- define `SECURITY_WIN32` globally in `curl_setup.h`.
  To make sure it applies to all includes.

- document which Windows headers require `SECURITY_WIN32`.

- stop suppressing MSVC warning:
  `C4201 is: nonstandard extension used : nameless struct/union`
  The warning is no longer seen in supported build envs with the current
  codebase.
  Follow-up to 8beff43559 #8419

- document why `SCHANNEL_USE_BLACKLISTS` is needed.

- just define `SCHANNEL_USE_BLACKLISTS`, drop the unnecessary value `1`.

- stop defining unused `SCH_CRED_MAX_SUPPORTED*` fallback macros.
  Follow-up to 8beff43559 #8419

- document why `subauth.h` is included (where missing).

- move and de-dupe `subauth.h` include into `curl_setup.h`, limit to
  Schannel builds.

- stop include `schnlsp.h`. It is a 1-to-1 compatibility wrapper for
  `schannel.h`.

- curl_sspi.h: clarify comment about `SP_NAME_` macros.
  They are local macros, their SDK names are different and curl does not
  use them.

- curl_sspi.h: drop superfluous includes `security.h` and `rpc.h`.

Cherry-picked from #20556

Closes #20564
