[BUILD] enable win32 llvm build (#4941)

from #2757

 * fix deprecation warning
 * use bash shell to fix `az storage ...` console  error.
* `-DLLVM_ENABLE_DIA_SDK=OFF` added to fix `DIA_SDK` dependency -
`"ninja: error: 'C:/Program Files/Microsoft Visual
Studio/2022/Enterprise/DIA SDK/lib/amd64/diaguids.lib', needed by
'D:/src/triton/python/build/lib.win-amd64-cpython-310/triton/_C/libtriton.pyd',
missing and no known rule to make it"`.

the latest windows llvm build is available at
https://github.com/wkpark/triton/releases/tag/llvm-82f5acfb-windows

It would be nice to have default llvm;mlir compiler on the official
trion build system for someone who trying to develop solve some windows
related issue even if windows is not officially supported.

p.s.: and I'd like to thank all triton developers for their hard work!
