[Build] Windows ARM64 build failure: undefined symbol __longjmp_wrapper in fast_setjmp_arm64.s

3rd/bee.lua/3rd/lua-patch/fast_setjmp_arm64.sを3rd/bee.lua/3rd/lua55/ldo.cと併せて調査し、エクスポートされるシンボルとそれらのWindows ARM64での参照に焦点を当てます。MSVC armasm64ビルドを実行し、その後、アセンブリフェーズが完了し、生成された実行可能ファイルがリンクされて実行できることを、fast_setjmpまたはfast_longjmpの期待される動作を変更せずに確認します。

Description:
When attempting to compile lua-language-server on Windows on Arm using the MSVC toolchain (armasm64), the build fails during the assembly phase of the bee.lua dependency.

The assembler throws an error because the file 3rd/bee.lua/3rd/lua-patch/fast_setjmp_arm64.s attempts to export a symbol that is never defined in the text area, while also failing to export fast_longjmp.

Environment:
OS: Windows 11 (Arm64)
Compiler: MSVC (Host: ARM64, Target: ARM64)
Tool: armasm64.exe

Proposed Workaround / Fix:
I was able to successfully generate the executable by modifying fast_setjmp_arm64.s as follows:

1. Removing the EXPORT __longjmp_wrapper line (as it has no corresponding label).
2. Adding EXPORT fast_longjmp to ensure the symbol is visible to the C code in ldo.c

Modified Assembly Header:

    EXPORT fast_setjmp
    EXPORT fast_longjmp  ; Added this
    ; EXPORT __longjmp_wrapper ; Removed this as it caused error A2023: undefined symbol: __longjmp_wrapper

Questions/Concerns:
While this allows the build to complete and the server to run, I am not 100% sure if:

1. __longjmp_wrapper was intended to be an alias for fast_longjmp for compatibility with specific Windows exception handling.
2. There is a specific reason fast_longjmp was omitted from the exports in the original ARM64 patch.

Could the maintainers verify if this is the correct way to align the ARM64 assembly with the Windows MSVC requirements?
