fix(ci): improve LLVM detection for Windows ARM64 release builds

The previous fix only checked 2 LLVM paths (Enterprise and BuildTools).
This update:
- Adds all Visual Studio editions (Enterprise, Professional, Community, BuildTools)
- Checks both 'Program Files (x86)' and 'Program Files' directories
- Falls back to searching for clang.exe recursively if not in standard paths
- As last resort, installs LLVM via chocolatey to ensure builds succeed

This should fix the 'failed to find tool clang: program not found' error
from cc-rs when building the ring crate on Windows ARM64.
