Log Message:
syncretro: build on Windows (MSVC, Win32), and per-platform install

Add the Windows half of the SyncRetro build, in the spirit of the sibling
doors (syncdoom/syncduke/syncconquer/syncmoo1). Win32 (x86) is the one supported Windows target: one Win32 binary runs on both a Win32 and a
Win64 Synchronet host (the DOOR32.SYS handle is 32-bit-significant and
crosses the process-bitness boundary), and a Win32 door loads a Win32
core .dll.

All of the door's Windows-vs-POSIX difference is confined to two files:

- syncretro_plat.c/.h -- the whole clock / sleep / non-blocking-socket
/ console-less-stderr seam over xpdev. sockwrap.h normalizes
WSAGetLastError() onto the POSIX errno values so ONE classify()
covers both platforms; io.c, input.c, door.c and main.c lose their
direct read/write/fcntl/clock_gettime/signal calls and carry no
#ifdef. door.c/config.c move onto xpdev stricmp()/FULLPATH()/fexist()
(MSVC has no strcasecmp/realpath/access). main.c's frame pacer, which
used clock_nanosleep(TIMER_ABSTIME), is reframed into a monotonic-
microsecond deadline plus a millisecond sleep.
- retro_core.c -- the core-load seam, dlopen/dlsym/dlclose vs
LoadLibrary/GetProcAddress/FreeLibrary. NOT routed through xpdev's
xp_dlopen(), which mangles the name and can't load a core by the
explicit path we hand it; the shim loads the path verbatim.

CMakeLists.txt gains an MSVC branch (ws2_32, CRT quiets, /Zi+/MAP crash symbolication, static libjxl from an x86-windows-static-md vcpkg prefix); build.bat mirrors the sibling doors.

Install layer (xtrn/syncivision): the binary and libretro core now live
where the lobby looks for them per platform, so one shared install (a BBS spanning a Linux box and a Windows host on the same mount) serves several
hosts without their same-named binaries colliding -- FLAT at the door
root on Windows (.exe/.dll never collide with a *nix host's names), or in
an <os>-<arch> sub-dir on *nix (linux-x64, ...), falling back to the flat
dir for the legacy symlink-deploy layout. lobby.js, deploy.js and
getcore.js derive that location from one sv_target() so they agree. deploy.sh/deploy.bat are replaced by deploy.js (a jsexec script, so it
shares the token code and can't drift from the lobby). getcore.js
downloads the FreeIntv core (GPLv2+) from the libretro buildbot, local-
first. install-xtrn.ini registers the lobby, which passes EX_NODISPLAY to bbs.exec() to hide the door's console (diagnostics captured to data/syncretro/syncretro_n<node>.log).

Verified on Windows (VS2022, Win32/Release via build.bat): clean build,
4/4 C unit tests pass, and an end-to-end capture-mode run loads a real
Win32 FreeIntv core, decodes a ROM, and renders a sixel frame. The shared
.c files changed for both platforms but were compiled under MSVC only --
not yet GCC/Clang.
