CI: windows: Force using LLVM 12

LLVM is moving to the 13 release, but LLVM-SPIRV is still so in the past.
Given that LLVM 12.0.0 is still not out (we are at 12.0.0-rc1 today),
use the `release/12.x` branch for LLVM.

We should also tag LLVM-SPIRV, but... it seems that they haven't caught up
yet, so keep using the master branch, but add a note for a future
committer.
