llvm doesn't exist for windows env

I would like to build my own client to add my own servers to avoid using renaming options for clients.

Thanks

Start by reproducing the documented Windows client build with the listed vcpkg command and compare the failure against the current MSYS2 package availability. Review the Windows build instructions and verify that the dependency and LLVM guidance is still accurate; done means a newcomer can follow the updated instructions successfully.
