The MSVC UWP job in CI did not actually enable UWP. Fix this and
the fallouts discovered after enabling it.
- GHA/windows: make sure to enable UWP in MSVC vcpkg UWP job.
Use the CMake options and C flags already used for mingw-w64, but use
`WINAPI_FAMILY_PC_APP` instead of the deprecated `WINAPI_FAMILY_APP`.
(The former is not supported by mingw-w64, so leave it there as-is.)
Follow-up to cb22cfca69#14077
- GHA/windows: by default the MSVC UWP job became 2x-3x slower than
others after actually enabling UWP. Most of it is caused by
CMake/MSBuild automatically building full APPX containers for each
`.exe` target. This includes 21 CMake feature detections. Each
detection app is built into a 15MB APPX project, with code signing,
logos, etc. Example:
https://github.com/curl/curl/actions/runs/12056968170/job/33620610958
Disable this overhead for curl build targets via custom
`CMAKE_VS_GLOBALS` options. I've found no way to apply them to feature
detection targets, so those remain slow.
- cmake: automatically enable Unicode for UWP builds. It's required.
Also stop enabling it manually in the existing CI job.

poll() on macOS 10.12 was deemed broken in 2016 when we discovered that
it misbehaves when provided with no sockets to wait for. The
HAVE_POLL_FINE is used to mark a poll() implementation that behaves
correctly: it *should* still wait the timeout time.
curl has therefore opted to use select() on Apple operating systems ever
since. To avoid the risk that this or other breakage cause problems.
However, using select() internally is also bad because it suffers from
problems when using file descriptors beyond 1024.
This change makes poll() used if it is present, but if there is no
sockets to wait for it avoids using poll() and instead falls back to
select() - but without any sockets to wait for there is no 1024 problem.
This removes all previous special-handling involving HAVE_POLL_FINE.

Sources used `lib/curlx.h` with both `ENABLE_CURLX_PRINTF` set and unset
before including it.
In a cmake "unity" batch where the first included source had it unset,
the next sources did not get the macros requested with
`ENABLE_CURLX_PRINTF` because `lib/curl.x` had already been included
without them.
Fix it by by making the macros enabled permanently and globally for
internal sources, and dropping `ENABLE_CURLX_PRINTF`.
This came up while testing unity builds with smaller batches. The full,
default unity build where all `src` is bundled up in a single unit, was
not affected.

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.

The wrong error code was checked on Windows on UNIX socket failures,
which could have caused all UNIX sockets to be reported as having
errored and the tests therefore skipped. Also, a useless error message
was displayed on socket errors in many test servers on Windows because
strerror() doesn't work on WinSock error codes; perror() is overridden
there to work on all errors and is used instead.

On Windows data can be lost in buffers in case of abnormal program
termination, especially in process chains as seen due to flaky tests.
Therefore flushing all buffers manually should avoid this data loss.
In the curl tool we play the safe game by only flushing write buffers,
but in the testsuite where we manage all buffers, we flush everything.
This should drastically reduce Windows CI and testsuite flakiness.

The runtests script now always performs variable replacement on the
entire test source file before the test gets executed, and saves the
updated version in a temporary file (log/test[num]) so that all test
case readers/servers can use that version (if present) and thus enjoy
the powers of test case variable substitution.
This is necessary to allow complete port number freedom.
Test 309 is updated to work with a non-fixed port number thanks to this.
