external/LuaJIT-2.1: switch to WohlSoft v2.1 fork tip @ dfcb8651 (2026-04-25)

Re-adopts the WohlSoft fork after the Feb 2023 swap to upstream sources
(485d7f2), pinning to current tip @ dfcb8651 (2026-04-25). WohlSoft
tracks upstream LuaJIT/LuaJIT v2.1 closely (7 commits behind as of
today), so this also catches ~3-4 years of upstream LuaJIT fixes since
the 2022 baseline, notably the recent JIT/interpreter consistency work.

WohlSoft's UTF-8 path patch ships in this drop via lj_fopen.c /
lj_fopen.h but stays dormant: CCCP's build doesn't define
LUAJIT_FORCE_UTF8_FOPEN, so _lua_fopen / _lua_freopen macro to plain
fopen / freopen, identical to upstream LuaJIT's Windows behavior.
Available as a future toggle if we want UTF-8 Windows paths.

Added lj_fopen.c to src/meson.build + libluajit.vcxproj. Preserves CCCP
build glue (meson.build, meson_options.txt, libluajit.vcxproj,
msvc-prebuild.bat, msvc-postbuild.bat). src/luajit.h regenerated from
the new luajit_rolling.h template (rolling version 1777102609 matching
dfcb8651).

Rebuilds _Bin/*.lib from the new source so Windows still links;
follow-up PR drops the prebuilts entirely and wires libluajit.vcxproj
into RTEA.sln.

Verified clean on Windows MSBuild (Final / Debug Full / Debug Minimal /
Debug Release, x64) + Linux Meson via WSL2. macOS-arm64 deferred to CI.
WohlSoft v2.1 is 7 commits behind upstream LuaJIT/LuaJIT v2.1 as of
2026-05-26 (recent sanitizer fixes); can sync in a follow-up if WohlSoft
hasn't picked them up by then.

------------------------------
+# LuaJIT + CMake & UTF8-paths-on-Windows
+There is the modified version of LuaJIT that has the next difference from the original version:
+* In addition to its default GNU Make-based build, there is a CMake-based build was added
+* Enforces the UTF-8 charset for file system-related functions to ensure the equal result on all supported platforms (without this addition, locale-depending ANSI charsets used on Windows) (You should specify the `-DLUAJIT_FORCE_UTF8_FOPEN=ON` CMake option to enable this feature)
+
+If you find a bug using CMake build, please **DON'T REPORT IT TO OFFICIAL LuaJIT developers**, as they refuse to take the CMake building system support. So, you MUST verify the [latest original version](https://github.com/LuaJIT/LuaJIT) using the GNU Make-based building system to ensure that the same bug gets reproduced too:
+* If the bug gets reproduced at both CMake and GNU-Make-based builds, feel free to report the bug to [official LuaJIT developers](https://github.com/LuaJIT/LuaJIT/issues).
+* If the bug gets reproduced at the CMake-based build only, however, doesn't reproduce at the official GNU-Make-based build, you [should report this bug to me](https://github.com/WohlSoft/LuaJIT/issues).
