LLVM 2.1.2 winget install on Windows is missing Arm64 builds

[marcpems]

The latest build of LLVM that has been submitted to winget is missing the Windows on Arm builds. This means that the x64 version of the tools are being installed on Arm machines instead of the Arm builds.

Repro:

• on a Windows 11 machine open a terminal prompt and type: winget install llvm.llvm
• wait for the installation to complete
• run: c:\program files\llvm\bin\clang --version

Expected:
output shows:
...
Target: aarch64-pc-windows-msvc

Actual:
output shows:
...
Target: x86_64-pc-windows-msvc

This needs to be resolved by the winget repo owner by manually submitting the additional Arm package.

ALSO: in future it would be better to automate the submission to Winget by using a yml script like this one from powertoys

@marcpems IMO winget pulls in LLVM installer from the upstream release page https://github.com/llvm/llvm-project/releases/tag/llvmorg-21.1.2. We recently hit a infrastructure issue and there was some delay publishing WoA 21.1.2 release and there is chance that the time winget pulled the release binaries WoA release was no uploaded by that time.

As far as I know, nobody in the LLVM community is involved in submitting packages to winget, so reporting an issue here isn't really going to do anything.
