Fetch LLVM release according to branch in llvm submodule (#418)

Browse Source 
This change is essential first step to unblock gracefully enable LLVM 21
in revive compiler as current action blindly fetched latest LLVM binary
from the list of releases on our page.
The change queries release version from the submodule and uses it. Next
step: build LLVM 21 release binary
Next next step: switch revive compile to LLVM 21 after all issues are
fixed
