LLVM WOA64/ARM64 clang-cl.exe is incorrectly detected as 32-bit x86

The WOA64 (Windows on ARM) LLVM compiler is incorrectly detected as "LLVM 32 bit based on MSVC2022" (x86-windows-msvc2022-pe-32bit) instead of aarch64 by Qt Creator. This means LLVM cannot be used for the ARM64 Qt toolchain

Steps to reproduce:

1. Install WOA64 version of LLVM: https://github.com/llvm/llvm-project/releases/download/llvmorg-17.0.6/LLVM-17.0.6-woa64.exe
2. Open Qt Creator and check Preferences > Kits > Compilers.
   • Expected: list contains an entry "LLVM WOA64 based on MSVC2022" or similar, but actually contains an entry "LLVM 32 bit based on MSVC2022" for "C:\Program Files\LLVM\bin\clang-cl.exe".
3. Select "LLVM 32 bit based on MSVC2022" as C/C++ compiler for "Desktop Qt 6.6.1 MSVC2019 ARM64" kit
   • Error (see attached screenshot): The compiler "LLVM 32 bit based on MSVC2022" (x86-windows-msvc2022-pe-32bit) cannot produce code for the Qt version "Qt 6.6.1 MSVC2019 ARM64" (arm-windows-msvc2019-pe-64bit).
